The plantar pressure distribution (af) and the structure behavior (gj) calculated by FE simulation. The bottom view (a) and top view (b) of plantar tissue, and the bottom view of ossature (c) with bare foot demonstrated that the load applied on plantar heel and forefoot was higher than other regions. The bottom view (d) and top view (e) of plantar tissue, and the bottom view of ossature (f) with heel cup showed that the red region in plantar heel disappeared and the color of calcaneus bone transferred from green to blue, indicating that the load decreased notably. The color that changed from red to blue represented the stress variation from large to small. The deformation of plantar soft tissue with bare foot (g) was more obvious than the tissue covered with heel cup (h). The same phenomenon could be observed on ossature structure between bare foot group (i) and heel cup group (j). The pattern made up of meshes represented the original shape, and the entity pattern represented the shape under compression
