Abstract

The main body of the foot (200) has heel (230) and toes (220) parts. An elongated ankle element (30), above the connecting-hole (260) in the heel part, has two longitudinal, facing ends (31) between which is an intermediate part (33). An ankle shaft (20) extends through the intermediate part and has a lower ball-shaped end beneath the intermediate part and which fits into a socket (24). The ankle element is supported by two spring elements (40) in the form of spiral springs (41) mounted inside the heel part beneath the ankle element and next to the facing ends. The socket is held inside the connecting hole by a holder unit (50) fixed on the heel part inside the connecting hole.
