Abstract
Insoles represent a mean by which humans can improve postural comfort or existence and manifestation of posture static and dynamic. The variety of materials and sizes for different kinds of foot insoles are for manufacturers a challenge in terms of getting products flexible, versatile and easily adaptable to a larger range of subjects. Biomechanical foot dysfunction influences plantar load distribution and mechanical tissue stress. Greater influence over plantar loads and tissue stress may lead to optimize the insole design to improve foot biomechanics. Some investigations founded that the use of cushioned insoles reduces the risk of stress fractures and injuries; other research has shown no protective effect. The use of cushioned or shock-absorbing insoles invoked reducing the impact forces associated with running, protecting against injuries. The paper emphasizes a new method for analysis of the insoles materials behavior in different alkalis and acids, similar to those encountered in real situations when walking and standing. The behavior study of composite structure insoles started to establish constructive variants and the modality of exposure of these samples at different degrees of softening in simple water, in water with salinity and under negative and positive temperature, also to mechanical stress.
Highlights
Insoles represent a multitude of means by which humans can improve comfort and postural dysfunctions existence and manifestation of a static posture and/or dynamic
The variety of materials and sizes as appropriate to different kinds of foot insoles are for manufacturers a challenge in terms of getting those products flexible, versatile and adaptable to a range of subjects as large [1]
As established in international standards there are a number of categories of shoes that protect human loco-motor system. ”Safety shoes or boots with compression protection are required for work where a heavy object or item may roll over or a heavy animal may step on the toe
Summary
Insoles represent a multitude of means by which humans can improve comfort and postural dysfunctions existence and manifestation of a static posture and/or dynamic. First the first step of studies 7 samples of insoles was choosing (Fig.1.) to be analyzed in different environmental conditions (immersion in water and water solution, cold/warm environment and mechanical pressure).
