Foot Dimension among Indian Population: A Pilot Study

Foot anthropometry involves measuring the dimensions and shapes of the human foot, crucial for designing footwear that improves athletic performance and reduces the risk of injuries by offering adequate support and matching natural biomechanics. This study aimed to gather foot anthropometric data from both males and females and compare foot dimensions between the two to develop specific footwear. A total of 204 male and female volunteers, with an average age of 28.20 ± 12.95 years, participated in the study, and 15-foot measurements were taken using 3D foot scanner equipment. All data was analyzed using SPSS software version 26. The Mann-Whitney U test was used to compare differences between the right and left feet of males and females. Significant differences were found in various measurements of the left feet, including 'foot length', 'foot width', 'heel circumference', 'toe circumference', 'waist circumference', 'ankle circumference', 'thumb height', 'toe width', 'heel center width', 'lateral malleolus length', 'medial malleolus length', 'Spherion height', and 'instep circumference'; however, no significant difference was observed in 'foot arch height'. This study also showed that all parameters differed significantly between the right and left feet in both males and females. The Kruskal-Wallis ANOVA test revealed no significant difference in ‘foot arch height’ between males and females, but thumb height did show a significant difference between the left and right feet of females. These precise anthropometric measurements are crucial for ensuring the proper fit of footwear, insights into this variability, allow makers to make footwear that accommodates a wide range of users enhancing control, stability, and response during daily activity. Different activity requires different leg movements and support, and precise foot anthropometry can help customize footwear to meet the unique requirements of each activity.

Effectiveness of footwear and foot orthoses in reducing medial metatarsophalangeal joint pressure in women with hallux valgus

BackgroundHallux valgus is a common condition where the subluxation of the first metatarsophalangeal joint and lateral deviation of the hallux at the interphalangeal joint creates difficulty with footwear fit. Footwear and foot orthoses are commonly prescribed nonsurgical treatments for hallux valgus. Research questionDo extra-width footwear and foot orthoses influence peak pressure at the medial aspect of the metatarsophalangeal and interphalangeal joints in women with hallux valgus? MethodsCommunity-dwelling women with symptomatic hallux valgus underwent gait testing when wearing their own shoes and when wearing extra-width footwear fitted with three-quarter length, arch-contouring prefabricated foot orthoses. Peak pressure (kPa) on the medial aspect of the metatarsophalangeal and medial interphalangeal joints and on the plantar surface of the foot (hallux, lesser toes, metatarsophalangeal joint 1, metatarsophalangeal joints 2–5, midfoot and heel) were measured using the novel pedar®-X system with the pedar® pad and pedar® insole, respectively (Novel, GmbH, Munich, Germany). Paired samples t-tests were used to calculate the differences between the two conditions, and the magnitude of observed differences was calculated using Cohen’s d. ResultsWe tested 28 participants (aged 44–80 years, mean 60.7, standard deviation 10.7). Compared to their own footwear, wearing the intervention footwear and orthoses was associated with a statistically significant decrease in pressure on the medial aspect of the metatarsophalangeal joint (58.3 ± 32.8 versus 42.6 ± 32.8, p=0.026, d=0.49), increased pressure under the midfoot (70.7 ± 25.7 versus 78.7 ± 23.6, p=0.029, d=0.33) and decreased pressure underneath the heel (137.3 ± 39.0 versus 121.3 ± 34.8, p=0.019, d=0.45). SignificanceThe intervention footwear and orthoses significantly decreased peak pressure on the medial aspect of the first metatarsophalangeal joint but had no significant effect on the interphalangeal joint. Further studies are required to determine whether these changes are associated with improvements in symptoms associated with hallux valgus.

Do foot type classifications differ between male and female netball players? A cluster analysis

We must better understand the foot type classifications of netball players to develop sex and size-specific shoe lasts. Five hundred and two representative-level netball players (n = 251 male; n = 251 female) had their feet three-dimensionally scanned. A validated MATLAB code was used to extract six different foot measurements from these scans automatically. We then used a two-step cluster analysis and chi-squared tests to classify foot types and determine the effect of sex on each cluster, respectively. Five foot types were identified (Extra long-and-wide, Long-and-wide, Flat, Tapered and Short-and-narrow), with sex significantly affecting foot type classification. The feet of players wearing smaller shoe sizes were often Short-and-narrow and Tapered, whereas the feet of players wearing larger sizes tended to be more Extra long-and-wide and Long-and-wide. These results highlight that netball players have a wide variety of foot types; manufacturers should use these data to develop future grading systems to improve the fit and functionality of netball-specific footwear.

Footwear, Orthoses, and Insoles and Their Effects on Balance in Older Adults: A Scoping Review.

Footwear, orthoses, and insoles have been shown to influence balance in older adults; however, it remains unclear which features, singular or in combination, are considered optimal. The aim of this scoping review was to identify and synthesise the current evidence regarding how footwear, orthoses, and insoles influence balance in older adults. Four electronic databases (MEDLINE, CINAHL, Embase, and AMED) were searched from inception to October 2023. Key terms such as "shoe*," "orthoses," "postural balance" and "older people" were employed in the search strategy. Studies meeting the following criteria were included: (i) participants had a minimum age ≥60 years, and were free of any neurological, musculoskeletal, and cardiovascular diseases; (ii) an active intervention consisting of footwear, foot orthoses, or insoles was evaluated; and (iii) at least one objective outcome measure of balance was reported. A total of 56 studies from 17 different countries were included. Three study designs were utilised (cross-sectional study, n = 44; randomised parallel group, n = 6; cohort study n = 6). The duration of studies varied considerably, with 41 studies evaluating immediate effects, 14 evaluating effects from 3 days to 12 weeks, and 1 study having a duration of 6 months. Seventeen different interventions were evaluated, including/consisting of textured insoles (n = 12), heel elevation (n = 8), non-specific standardised footwear and changes in sole thickness or hardness (n = 7 each), sole geometry or rocker soles, contoured or custom insoles and high collar height (n = 6 each), insole thickness or hardness and vibrating insoles (n = 5 each), outsole tread (n = 4), minimalist footwear and slippers (n = 3 each), balance-enhancing shoes, footwear fit, socks, and ankle-foot orthoses (n = 2 each), and eversion insoles, heel cups, and unstable footwear (n = 1 each). Twenty-three different outcomes were assessed, and postural sway was the most common (n = 20), followed by temporo-spatial gait parameters (n = 17). There was uncertainty regarding intervention effectiveness. Overall, features such as secure fixation, a textured insole, a medium-to-hard density midsole and a higher ankle collar, in isolation, were able to positively impact balance. Conversely, footwear with an elevated heel height and the use of socks and slippers impaired balance. There is a substantial body of literature exploring the effects of footwear, orthoses, and insoles on balance in older adults. However, considerable uncertainty exists regarding the efficacy of these interventions due to variability in methodological approaches. Further high-quality research is necessary to determine whether a singular intervention or a combination of interventions is most effective for enhancing balance in older adults.

Sensory and Functional Recovery after Suprafascial Free Flap in Foot and Ankle Reconstruction

Abstract Background The goals of foot and ankle defect reconstruction include weight-bearing and shearing tolerance, good mobilization, regaining protective sensation, and good contour for footwear fitting. This study reports the outcomes of foot and ankle defect reconstruction with suprafascial free flaps relative to sensory and functional recovery. Methods Eleven suprafascial free flaps were performed, which were supra-Scarpa fascial flaps in seven cases. Sensory recovery was assessed by Semmes-Weinstein monofilament test (SWMT), and functional outcomes were measured using the Foot and Ankle Ability Measure (FAAM) questionnaire at preoperative and subsequent visits. Results Eleven cases (age range: 21–83 years, seven males, mean body mass index: 24.8 kg/m2) were operated and the mean defect size was 109.8 cm2. The anterolateral thigh, medial sural artery perforator, and superficial circumflex iliac artery perforator flaps were used. The mean flap thickness was 0.8 cm. Average flap harvesting time and operative time were 83.9 and 452.0 minutes. Half of cases achieved 10 g SWMT (two cases regained baseline sensation) by 6-months post-operation, and all cases regained either 10 g SWMT or baseline sensation within 12 months. Significant improvement in the activities of daily living (ADL) and sports subscales was observed at 3 months (p < 0.05). Significant improvement in the global function rating scale for both ADL and sports was achieved by 6 months (p < 0.05). None experienced the recurrent ulcer. Conclusion Suprafascial free flap is a good reconstruction strategy for managing complex foot and ankle defects that yields favorable outcomes including adequate protective sensation and significant functional improvement.

Study on the Health Impacts on Workers in Small Scale Industry

This journal speaks the significant of Peripheral Artery Disease, Chronic fatigue syndrome, Correct footwear fitting. have emerged as leading causes of morbidity and mortality in developed and developing regions of the world. The disease burden attributed continues to increase worldwide, with cardiovascular diseases the leading cause of mortality and morbidity. Chronic fatigue syndrome, also called myalgic encephalomyelitis, is a complex multisystem disease commonly characterized by severe fatigue, cognitive dysfunction, sleep problems, autonomic dysfunction, and post-exertional malaise severely impairing activities of daily living. Footwear fitting is acknowledged as being vitally important as in most cases fit governs function. This means that footwear cannot fulfil its intended purpose if it does not fit the foot correctly.

Searching for online information on the fit of children’s footwear during the COVID-19 pandemic: an analysis of Google Trends data

BackgroundSelecting footwear with appropriate fit in children is challenging due the changes with foot size and dimensions which occur throughout childhood. Access to appropriate footwear is important but recent challenges with the COVID-19 pandemic resulted in closure of retail stores for prolonged periods where parents/carers could not physically purchase footwear for their children and the footwear industry suffered disruption to their supply chain, and falls in retail sales. Simultaneously increased use of social media platforms for health information seeking throughout the pandemic have been documented. This likely would have included parents/carers seeking information online to support footwear purchases for their children. The primary aim of this work was to explore how searches for online fitting information for children changed throughout the COVID-19 pandemic lockdown periods. A secondary aim was to identify how searches were influenced by footwear style.Methods We employed Google Trends to obtain search engine traffic related to footwear fitting information for children. We collected data spanning the three years pre, during and post the main national lockdown for three eight-week windows: (1) first eight weeks of the U.K. national lockdown; (2) the first eight weeks of the calendaryear; (3) the eight weeks leading up to children going back-to-school for the new academic year in the U.K. The search terms reflected parents/carers searching for footwear fit information relating to children and were grouped by style of footwear: children, infants, babies and toddlers as well as school shoes.ResultsWe identified increased searching for footwear fit information for children during the pandemic, which reduced following post pandemic in all except the searches which related to school shoes. We saw reductions in searching related to fit of school shoes as schools closed indefinitely and an increase in online searches with the pandemic. This was also maintained post-pandemic despite shops reopening, suggesting that some of these changes in information reflect new consumer behaviours which may continue. Conclusions Increased searches for online resources regarding footwear fit highlights the importance of ensuring high quality accessible online information on footwear fit is available to support those buying footwear for their children.

How to measure children’s feet: 3D foot scanning compared with established 2D manual or digital methods

BackgroundIn infants and young children, a wide heterogeneity of foot shape is typical. Therefore, children, who are additionally influenced by rapid growth and maturation, are a very special cohort for foot measurements and the footwear industry. The importance of foot measurements for footwear fit, design, as well as clinical applications has been sufficiently described. New measurement techniques (3D foot scanning) allow the assessment of the individual foot shape. However, the validity in comparison to conventional methods remains unclear. Therefore, the purpose of this study was to compare 3D foot scanning with two established measurement methods (2D digital scanning/manual foot measurements).MethodsTwo hundred seventy seven children (125 m / 152 f; mean ± SD: 8.0 ± 1.5yrs; 130.2 ± 10.7cm; 28.0 ± 7.3kg) were included into the study. After collection of basic data (sex, age (yrs), body height (cm), body weight (kg)) geometry of the right foot was measured in static condition (stance) with three different measurement systems (fixed order): manual foot measurement, 2D foot scanning (2D desk scanner) and 3D foot scanning (hand-held 3D scanner). Main outcomes were foot length, foot width (projected; anatomical; instep), heel width and anatomical foot ball breadth. Analysis of variances for dependent samples was applied to test for differences between foot measurement methods (Post-hoc analysis: Tukey-Kramer-Test; α=0.05).ResultsSignificant differences were found for all outcome measures comparing the three methods (p<0.0001). The span of foot length differences ranged from 3 to 6mm with 2D scans showing the smallest and 3D scans the largest deviations. Foot width measurements in comparison of 3D and 2D scans showed consistently higher values for 3D measurements with the differences ranging from 1mm to 3mm.ConclusionsThe findings suggests that when comparing foot data, it is important to consider the differences caused by new measurement methods. Differences of about 0.6cm are relevant when measuring foot length, as this is the difference of a complete shoe size (Parisian point). Hence, correction factors may be required to compare the results of different measurements appropriately. The presented results may have relevance in the field of ergonomics (shoe industry) as well as clinical practice.

Analysis of hallux valgus angles automatically extracted from 3D foot scans taken in North America, Europe, and Asia

The forefoot is the foot part most affected by ill-fitting shoes. Footwear fitting considers the measurements of length, width, and arch length. Toe shape has not yet been used in sizing feet and fitting shoes. This study aims to investigate the variation in toe shape, as measured by the hallux valgus angle. An automatic and reproducible hallux valgus angle measuring method using 3D foot scans with no palpation markers is proposed and applied to about half a million samples collected across North America, Europe, and Asia. The measuring method is robust and can detect the medial contour along the proximal phalanx even in extreme cases. The hallux valgus angle has a normal distribution with long tails on both sides in the general population. Large dispersions of HVA values were observed for both genders and in all three geographical regions. Practitioner summary: The hallux valgus angle has a broad distribution in the general population. Females have larger hallux valgus angles than males, and people from Asia have larger hallux valgus angles than people from North America and Europe. Shoe toe boxes should be designed to fit the actual shapes of shoppers’ toes. The proposed method for measuring HVA opens a new opportunity to study the causal relationship between shoe wearing habits and HVA on a large scale.

Foot deformation analysis with different load-bearing conditions to enhance diabetic footwear designs.

In-depth analyses of foot surface measurements upon weight bearing are crucial to understand how the dorsal and plantar surfaces of the foot deform during motion to enhance the fit of footwear, which is particularly important for diabetic patients with stringent fit requirements to redistribute the plantar weight forces. This study analyzes diabetic foot deformations under 3 different weight bearing conditions (no weight bearing, half weight bearing, and 80% weight bearing) by using a novel foot scanning method that enables efficient scanning of the dorsal and plantar surfaces of the foot simultaneously. The feet of 48 patients with diabetes mellitus (DM) are scanned. With increased load on the feet, the width of the forefoot increases by 9.7%-10.4%, height of the midfoot decreases by 15.1%-18.2%, forefoot and midfoot rotate to the medial side by 16.9%-23.9% while the rearfoot rotates to the lateral side by 15.2% simultaneously, and the plantar of the foot increases contact with the floor by 11.4%-23.0%. Gender differences in foot shape are also found between males and females, males have a broader foot than females for the same foot length. Precise anthropometric information of foot changes and deformation therefore enables adequate foot protection, fit and comfort when designing footwear. This research contributes to shoe design considerations that focus on the deformation of the foot under different loads.

Evaluation and optimisation of a footwear assessment tool for use within a clinical environment

Footwear has been documented as a significant factor in the aetiology of foot pain in the general population. Assessing footwear in a clinical setting continues to be practitioner specific and there is limited guidance to direct advice. Health professionals must have access to clinically appropriate and reliable footwear assessment tools to educate patients on healthier footwear choices. The primary aim of this study was to critique what elements should be in a footwear assessment tool with a secondary aim of testing the agreed tool for validity.A combined Nominal Group Technique and then a Delphi technique from purposively sampled experts of foot health professions were employed to critique elements of footwear assessment. The agreed tool was then tested by practising podiatrists on 5 different shoes to assess the validity and reliability of the measures.Twelve test evaluation criteria were identified receiving significant ratings to form the final footwear assessment tool consisting of five footwear themes. Application of the tool in a clinical setting validated the themes of footwear characteristics, footwear structure, motion control and wear patterns. However, the assessment of footwear fit was not reliable.The footwear tool was refined based on the collective consensus achieved from the rounds creating a more clinically appropriate tool. The validity of this tool was assessed as high in some of the themes but for those that were lower, a training need was identified.

Relationship of the Use of Short Footwear with the Development of Hallux Valgus in a Sample of Andalusian Schoolchildren

Background: Several studies have shown the relationship between poor footwear fit and the risk of feet deformities. The available evidence seems to show that the development of hallux valgus deformity in the feet of schoolchildren may be related to the use of shoes that are poorly fitting in length. The objective of this cross-sectional study was to analyze the relationship between poor footwear fit in length and risk of developing hallux valgus. Methods: Using an instrument that was designed and calibrated for this purpose, maximum foot length was obtained and compared to the inner length of the shoe in 187 schoolchildren. Hallux valgus angle (HVA) was measured on weight-bearing podogram image obtained from the longest foot in 188 schoolchildren. Results: By default, the footwear was poorly fitting in length (too short or close-fitting) in 38.5% of the schoolchildren, with boys having the worst footwear fit; though no significant differences stood out. (p = 0.276). Regarding the HVA, no significant differences were recorded according to age or gender (p = 0.573). A strong correlation was observed between too-short footwear and the increase in HVA in 10-year-old boys (r = 0.817; p = 0.025) and in 9-year-old girls (r = 0.705; p = 0.005). Conclusions: Inadequate footwear fit in length may be a predisposing extrinsic risk factor for the development of hallux valgus in schoolchildren of both sexes. Results of the present study demonstrate the need to adapt the sizes of footwear to the rapid increase in foot-length that occur at puberty to avoid the risk of developing hallux valgus, especially at the ages of onset pubertal foot growth.

Malleoli positions do not scale with foot length: implications for footwear comfort

Footwear fit is one of many factors that contribute to overall comfort. Researchers have improved this fit by matching foot anthropometrics, from 3 D scans, to shoe lasts (Zhang et al., 2012). Impr...

The impact of functional excess of footwear on the foot shape of 7-year-old girls and boys.

BackgroundProperly fitted shoes can support the development of growing feet and prevent problems and pathologies, not only in childhood, but also in adulthood. This points to the need to conduct research on the impact of shoe fitting on the structure of the foot in order to raise awareness and importance of this problem, to enable proper decisions regarding the purchase and use of shoes. The aim of this study was to analyze indoor footwear fit and its impact on foot structure in 7-year-old schoolchildren.MethodsThe CQ-ST podoscope and the Clevermess device were used for measurements. The analysis was carried out using the Mann Whitney U test, Wilcoxon signed-rank test, Chi-square test, regression analysis.ResultsAbout 40% of girls and boys had shoes that were incorrectly fitted in length, while as many as 74% of girls and 66% of boys wore shoes that were incorrectly fitted in width. Regression analysis demonstrated a statistically significant influence of the footwear length on longitudinal arch of the right and left foot and the transverse arch of the right foot. In boys, the length of the shoes shows associations with the right and left hallux valgus angle.ConclusionA significant percentage of the studied 7-year-olds, regardless of gender, wears inappropriately fitted shoes. In both sexes, the length of the footwear influenced the longitudinal arch of the right and left foot and the transverse arch of the right foot. Due to the deformity of the first metatarsophalangeal joint, the boys with hallux valgus require footwear which is wider and therefore their shoes need to be bigger in size.

Differences in foot dimensions between children and adolescents with and without Down syndrome

Purpose This study compared the differences in foot dimensions between children with and without Down syndrome using three-dimensional (3D) foot scans. Methods 51 children with and 51 children without Down syndrome had a 3D scan taken of their right foot to compare the absolute and normalised (for height or foot length) measurements. Results Normalised foot length was shorter in children with Down syndrome (MD −11.62 mm, 95% CI −15.06 to −8.18, p < 0.001). When normalised for foot length, ball of foot length (MD 2.87 mm, 95% CI 1.17 to 4.58, p = 0.001), diagonal and horizontal foot width (MD 3.65 mm, 95% CI 1.65 to 5.66, p < 0.001; MD 4.80 mm, 95% CI 2.88 to 6.72, p < 0.001, respectively), ball and instep girth (MD 10.60 mm, 95% CI 5.96 to 15.25, p < 0.001; MD 7.92 mm, 95% CI 3.02 to 12.82, p = 0.002, respectively) and fifth toe height (MD 3.14 mm, 95% CI 2.22 to 4.07, p < 0.001) were greater in children with Down syndrome. Conclusions Children with Down syndrome have shorter, wider feet with greater girth and fifthtoe height measurements relative to children without Down syndrome. These findings have implications for footwear fit and the manufacturing of population-specific footwear. IMPLICATIONS FOR REHABILITATION Footwear-fitting issues arise as a result of the unique foot shape of children with Down syndrome. There are substantial variations in the foot shape of children with and without Down syndrome. Children with Down syndrome require wider, deeper footwear at a given length to accommodate their foot dimensions. These findings have implications for the manufacturing of population-specific footwear.

Archetype analysis: A new subspace outlier detection approach

The problem of detecting outliers in multivariate data sets with continuous numerical features is addressed by a new method. This method combines projections into relevant subspaces by archetype analysis with a nearest neighbor algorithm, through an appropriate ensemble of the results. Our method is able to detect an anomaly in a simple data set with a linear correlation of two features, while other methods fail to recognize that anomaly. Our method performs among top in an extensive comparison with 23 state-of-the-art outlier detection algorithms with several benchmark data sets. Finally, a novel industrial data set is introduced, and an outlier analysis is carried out to improve the fit of footwear, since this kind of analysis has never been fully exploited in the anthropometric field.

Focusing research efforts on the unique needs of women prosthesis users.

Women with lower limb loss represent a relevant and growing patient cohort with unique rehabilitation needs. These needs are emphasized in a growing body of literature and the most recent Veteran Affairs/Department of Defense clinical practice guidelines. Women with limb loss experience greater dissatisfaction with prosthetic fit, appearance, and types of footwear they can use. There is a lack of prosthetics solutions to accommodate the desire of women to wear different footwear varieties, including high heels. The choice to wear a variety of footwear is important to attire and hence community participation. Despite these recognized challenges, women are still underserved in prosthetics research, which limits available information to guide the rehabilitation process. This narrative review describes considerations of lower limb prosthesis prescription and use by women, and examples of current research to address these topics. Research efforts are beginning to explore factors that contribute to prosthetics prescription for women, and design creative prosthetics solutions to expand the range of available footwear options. Research is still needed to characterize the types of footwear women with limb loss prefer to use, and the effects of prosthesis designs, footwear, and lower limb loss on women mobility outcomes and community participation. Through targeted research initiatives, scientists and clinicians can be responsive to the specific needs of women to provide evidence-based guidelines for prosthetics prescription and improve the patient-centered care after limb loss.

Musculoskeletal disorders, foot health and footwear choice in occupations involving prolonged standing

Occupations that involve prolonged periods of standing and maintaining an upright posture are associated with an increased risk of work-related musculoskeletal disorders (WMSD), particularly of the lower back and lower extremities. Identifying factors that impact WMSD is therefore important, but the foot and footwear have been largely ignored to date. Therefore, this study aimed to assess the prevalence of WMSD of the lower back and lower extremity with emphasis on foot health and the impact of footwear. A cross-sectional questionnaire was completed by 147 surgical workers who were standing for long periods in their working day. It assessed job demands, individual characteristics, WMSD prevalence, psychosocial factors and footwear, with a multivariate analysis to identify relationships between variables. Results found the low back was the most predominant area of WMSD (71%), but the foot had the second highest prevalence (55%). The plantar foot surface was the main region of foot pain with everyone that experienced foot pain reporting it under the heel, ball of foot or arch region. Footwear was recognised as an influencing factor on WMSD by the participants as well as by the multivariate analysis, highlighting the importance of exploring footwear to reduce WMSD. Footwear comfort, footwear fit, footwear choice and the provision of footwear by employers were all identified as important factors to consider in relation to WMSD and foot health. Relevance to industryFootwear is related to WMSD which are seen in the majority of workers undertaking prolonged standing. Employers of these workers and footwear suppliers should consider footwear comfort, particularly its fit and individual preference for footwear characteristics including underfoot cushioning and support. This should also include consideration of the range of footwear available and how it is selected by workers.

Dependences between the footwear fitting and feet structure in girls of third-grade primary school

Background: The study aimed to study dependences between the footwear fitting and feet structure in girls of third grade of primary school. Material and methods: The research tool was the podoscope CQ-ST. The footwear fitting to the feet of the examined children was tested using the Clevermess device. Results: Statistically significant relationships between the frequency of varus deformity of the Vth toe of the right foot and the width fitting of the outdoor footwear were found (p=0.027). Statistically significant relationships between the length of the indoor footwear and the heel angle (γ) of the left foot have also been noted (p = 0.038). Conclusions: Conclusions: Children with a wider forefoot wear longer shoes, which is why there is a need to take into account differences in the foot width in the production of footwear used indoors. The use of too short footwear, without free space that is necessary for the proper setting of the foot during movement or load, is a factor leading to excessive lateral arching. Wearing too wide shoes affects the formation of varus deformity of the Vth toe of the right foot.

Influence of footwear fitting on feet morphology in 9\u2009year old girls

BackgroundThe human foot is shaped throughout all life in a way that is individual for every human being. Footwear fitting in the process of foot development is the issue covered by a limited range of empirical studies. This prompted the authors to undertake this subject of the study aimed at the influence of fitting of regularly worn inside the school footwear on feet morphology in primary schoolgirls.MethodsThe study group comprised 100 girls aged 9. Feet characteristics were recorded by CQ-ST podoscope. The footwear fitting to the feet of the examined girls was tested using the Clevermess device. The data were analyzed based on the Student’s t test, Wilcoxon test and regression analysis.ResultsAppropriately fitted right indoor footwear was worn by 48% of the subjects while the left one by 43% of the group. Appropriate fitting in relation to the left and right foot width was noted in 23% of the group. The statistically significant combined effect of predictors characterizing footwear on the value of Wejsflog index of the right (p < 0.001) and left (p < 0.001) foot and influence of the length excess on the heel angle of the left foot (p = 0.006) were found.ConclusionsMost examined girls wear poorly fitted indoor footwear. The length excess of the indoor footwear has connections with the Wejsflog index of the right and left foot and the heel angle of the left foot. The larger the length excess, the lower the transverse arch. In the production of indoor footwear the differences in the feet width should be taken into account.
