Abstract
The plantar pressure distributions for a 42 normal feet were collected during barefoot standing using a pressure platform. From these data, a pattern foot, for this study, was characterized. A 3-D finite element foot model was generated and two insole models were simulated. The current paper investigated the effects of different insole models in pressure plantar distribution, using silicon of the foot-shoe interface. In addition, this study proposed a new concept for the bony structure of heel design, generated based on the x-ray and anatomical images. The finite element analysis implies better distribution of plantar pressure with flat insole than insole concave. Both insoles reduced plantar pressure of approximately 30%. The technique presented is an ideal clinical tool to explore the effects of various insoles models.KeywordsPlantar pressureFinite element methodSilicon insoleStress distribution
