Subtalar joint
Articulatio subtalaris
Reviewed by Dr. Ryan Rietz, D.P.T. and Dr. John Breyman, D.C.
The joint between the talus and the heel bone, just below the ankle. This is where the foot rolls in and out — the motion people mean when they talk about pronation and supination. It sits on an oblique axis, so it does not move in a single plane: one movement tips the foot in three directions at once. It is the foot's adaptor. On landing it unlocks and lets the foot mould to the ground; at push-off it locks and turns the foot into a rigid lever.
