An artificial foot device may include a talus body (100), a core (200) operatively coupled with the talus body by a first joint (12), and a toe (300) operatively coupled with the core by a second joint (14). A vertical restraint link (5000) between the toe and the core and provides a coupling for the second joint. A toe insert (3000) limits motion of the toe relative to the core. A toe bushing (1000) receives a tension member for operatively coupling the toe to the talus body. The vertical restraint link, toe insert and bushing constrains relative movement between the core and the toe at the second joint. Relative movement of the core and the talus body at the first joint is guided and constrained by pivot bearings (7000). Constrained relative movement between the talus body and the core corresponds to a coordinated movement of a first joint and a second joint during ambulation of a natural human foot.
