Motion
The joint allows inversion and eversion of the foot, but plays no role in dorsiflexion or plantarflexion of the foot.
It is considered a plane synovial joint, also commonly referred to as a condyloid joint.
The subtalar joint can also be considered a combination of the anatomic subtalar joint discussed above, and also the talocalcaneal part of the talocalcaneonavicular joint. This is the more common view of the subtalar joint when discussing its movement. When both of these articulations are accounted together, it allows for pronation and supination to occur.

Famous quotes containing the word motion:
“All the phenomena which surround him are simple and grand, and there is something impressive, even majestic, in the very motion he causes, which will naturally be communicated to his own character, and he feels the slow, irresistible movement under him with pride, as if it were his own energy.”
—Henry David Thoreau (1817–1862)
“If we shall stand still
In fear our motion will be mocked or carped at,
We should take root here where we sit, or sit
State-statues only.”
—William Shakespeare (1564–1616)
