Which joint is weak on all sides?
The joint capsule of the talocalcaneonavicular joint is weak on all sides, except the posteroinferior border which is shared with the anterior part of the capsule of the talocalcaneal/subtalar joint. The calcanecuboid joint is exclusively confined to its joint capsule, which encloses the joint on all sides.
What is the transverse tarsal joint?

What is the junction between the hind and midfoot?
The junction between the hind and midfoot is termed the Chopart's joint, which includes the talonavicular and calcaneocuboid joints. Forefoot: The forefoot is the most anterior aspect of the foot. It includes metatarsals, phalanges (toes), and sesamoid bones.
What is the most posterior aspect of the foot?
Hindfoot: Hindfoot, the most posterior aspect of the foot, is composed of the talus and calcaneus, two of the seven tarsal bones. The talus and calcaneus articulation is referred to as the subtalar joint, which has three facets on each of the talus and calcaneus.
Why is subtalar pronation important?
Subtalar pronation has a shock absorbing effect during initial heel contact. Pronation is also necessary to enable rotation of the leg and to absorb the impact of this rotation. Subtalar pronation plays a role in shock absorption through eccentric control of the supinators. On the other side, the joint of Chopart becomes unlocked so that the forefoot can stay loose and flexible. In midstance, the foot needs mobility to adapt to variation in surfaces.
