Considering the morphological characteristics of the foot, the most prone to injury were the varus hindfoot (87.5%) and the cavus arch (71.4%): these two conditions are often associated in the
cavus foot. The fact that
cavus foot is more prone to injuries in general is not surprising, due to its less flexible structure.
An overly tight tendon of the peroneus longus muscle is typical of the rigid pes
cavus foot type, and easily locks the first ray down into plantar flexion, making the foot even more rigid and shifting weight onto the lateral arch.65 In dance, this leads to poor technique, especially landings in demi-plie that lack shock absorption.
