The basic support for the medial arch is derived from the tibialis anterior, “…which arises from the anterior compartment just lateral to the tibia, and passes just in front of the ankle joint to attach into the joint between the first cuneiform and the first metatarsal bones†(Myers, 1997, para. 43). Due to some weak links in the medial arch, the resilient pull provided by the tibialis anterior functions as a muscular support to the health and wellbeing of the medial arch.
The peroneus longus, on its part, originates from the fibular head and travels down just behind the lateral malleolus. At this juncture, it dips more deeply, passing under the cuboid, and ultimately attaching purposively “…on the lateral side of the first cuneiform-first metatarsal joint†(Myers, 1997, para. 44). This muscle is known to assist in the formation and strengthening of the arches of the foot. In particular, peroneus longus support and sustains the lateral and transverse arches by elevating up against the cuboid or by compressing the cuneiform bones and the cuboids together
