The arch is further supported by the plantar aponeurosis, by the small muscles in the sole of the foot, by the tendons of the Tibialis anterior and posterior and Peronæus longus, and by the ligaments of all the articulations involved.

What supports the medial longitudinal arch?

The medial longitudinal arch is supported both passively and actively by ligaments, plantar aponeurosis, and muscles. 8 The main static supports of the medial longitudinal arch are the plantar aponeurosis, the long and short plantar ligaments and the plantar calcanonavicular ligament, also known as the spring ligament.

What happens when ligaments are damaged?

Ligaments support and strengthen joints. Their main function is to keep the bones of the skeleton in proper alignment and prevent abnormal movements of the joints. A torn ligament makes the joint harder to move. It makes the joint looser than usual, which means you are unable to move the joint normally.
