Artificial foot comprises a lower connecting element (8) extending into the heel region. Preferred Features: An upper connecting element (3) can be adjusted in the longitudinal direction and has a hydraulic cylinder. A damping arrangement is arranged between the lower connecting element and a connecting part (1). The damping properties of the connecting elements can be adjusted depending on measured loading and/or positional states.一種義足，具有一用於接一小腿部的接頭部(1)及一足前部(6)，該足前部利用一上聯接元件(3)及一下聯接元件(8)與該接頭部(1)樞接，使該接頭部(1)的角度位置控制足前部(6)的角度位置，其中該聯接部(30)(8)之一延伸到一直到義足的踵區域進去，其中用以下方式防止在負荷時有效足長度改變，該下聯接元件一直延伸到該踵區域進去。如此可避免在負荷時有效的足長度改變。
