Orthopedic sole for supporting foot, has front unit that is elastically deformable to reform front arch every time foot is pressed, where unit has metallic strip that produces spring effect

摘要

The sole (1) has a transversal front unit (2) that is provided with lateral flanges (2b, 2c) whose configuration resembles metatarsal heads. The front unit is elastically deformable, and produces a spring effect at the level of flanges for reforming the front arch every time the foot is pressed. The unit has a metallic strip that extends partly in each flange and produces the spring effect.
