In this study, effect of a new foot pressure redistribution method is tested. A female subject was asked to stand on prepared clay prototypes and slowly load on foot. Then, shapes of pressed feet under different loadings were recorded by the footprints which were left on the deformed clay prototypes. Then scan and rebuild the model of the footprints. The shape of deformed total contact insole (DTCI) based on these footprints is available in this way. Repeat the loading process on DTCI. Forces distribution results were measured and reflected by the pressure measurement paper between foot and insole. It's found that DTCI provides a larger contact area and a smaller local peak pressure than traditional total contact insole in static situations. The method is expected to relieve peak pressure of all three parts of foot-shoe interface. It's found that DTCI is very efficient in terms of peak pressure relief and redistribute the pressure beneath foot. It can be used as a tool to improve some characteristics of shoes with obvious side effects.
