A foot prosthesis having a lower-leg connection part, a foot part, a connecting element with a joint function which connects the lower-leg connection part to the foot part, and a release device, which controls movement of the foot part in relation to the lower-leg connection part. The release device includes an inhibiting device that is designed in such a way that a dorsal extension motion of the foot part in relation to the lower-leg connection part in an angular range from a maximal plantar flexion position to a zero position is inhibited less intensely than a dorsal extension motion of the foot part from the zero position.
