Which muscles are the prime movers for ankle eversion?

Explanation:
Ankle eversion is produced by turning the sole of the foot outward, which is driven mainly by the fibular (peroneal) muscle group. The primary movers are the peroneus longus, peroneus brevis, and peroneus tertius. They pull on the lateral side of the foot to evert the subtalar joint. Peroneus longus and peroneus brevis also tend to assist with plantarflexion, while peroneus tertius assists with dorsiflexion. The other muscles listed do not primarily evert the ankle: tibialis posterior inverts the foot; gastrocnemius primarily plantarflexes the ankle; flexor digitorum longus mainly flexes the toes and assists with plantarflexion, not eversion.
