0 relating to the calcaneus (= the heel bone) and the cuboid bone (= a bone on the outer side of the foot)
Along with the transverse tarsal joint (i.e. talonavicular and calcaneocuboid joint), the subtalar joint transforms tibial rotation into forefoot supination and pronation.
The favored idea is that the cuboid bone is forcefully everted while the calcaneus is inverted resulting in incongruity at the calcaneocuboid joint.
