Studying Maximum Plantar Stress per Insole Design Using Foot CT-Scan Images of Hyperelastic Soft Tissues

Figure 5

Variation of maximum stress value by changing the degrees in metatarsal, mid foot, and heel regions for custom-molded insole. Increase of insole degree (or the heel height) does not necessarily reduce the maximum stress in foot; the recommended range is around 0.2° to 0.4°.
