Changes in forefoot plantar pressure with shoe of different heel height

The effect of heel height on plantar pressure of human forefoot was tested by using the Novel insole system. The test results demonstrate that the plantar pressure difference of each part of forefoot in walking state was ordered from large to small as the second metatarsal>the first metatarsal>the third metatarsal>the first toe≫the fourth metatarsal≫the fifth metatarsal>the region including second to fifth phalanx. According the plantar pressure distribution of forefoot, pressure center of forefoot was moved from lateral plantar to medial plantar with the increasing of heel height.
