The human foot is made up of 26 bones, 33 joints and over 100 ligaments, muscles and tendons. They are the foundation of your entire body and as such need to be healthy, balanced and correctly aligned.
When you walk or run, there are two principal biomechanical movements: pronation and supination.
Pronation is the rotation of the foot inward and downward so that the medial side of the foot bears the body's weight. This is the body's natural way to absorb shock and adapt to uneven surfaces.
Over-pronation or when the foot rolls inward excessively distributes weight unevenly and can expose the body to injuries.
Supination is the rotation of the foot outward so that the outer edge of the foot bears the body's weight.Supination is roughly speaking the opposite of pronation.
Supination is the body's natural way to convert the foot into a rigid lever for propulsion. However, supination can be harmful if it is the principal biomechanical movement of the foot. This is because it impairs the body's ability to absorb shock and the foot to rebound naturally.
With a neutral foot type, the outside of the heel strikes the ground first. The foot rolls inward slightly to efficiently absorb shock and allow the foot and ankle to properly support the body. The foot pronates, but not excessively.
Maintaining a neutral foot position is essential to minimizing foot fatigue and improving shock absorption.
Arches of the foot
The foot has a tripod formation comprising three arches which allow it to support the weight of the body efficiently. The medial, transverse and lateral arches are formed by the tarsal and metatarsal bones and strengthened by the ligaments and tendons of the foot.
Medial longitudinal arch (A - B)
Commonly known as the medial arch, the main function of the medial arch is to absorb shock. Low medial arches can result in the risk of over-pronation, a type of excessive foot motion, which in turn can result in instability or poor shock absorption.
FootBalance Custom Insoles support your medial arches, dynamically activating them to help prevent them from falling further and in some cases helping to rehabilitate them.
Transverse Arch (B - C)
Many forefoot problems like hammertoes, bunions and numbness can be linked to a fallen transverse arch. Supporting the transverse arch may offer relief by increasing room for the blood vessels and nerves.
Transverse arch supports can be moulded into FootBalance Custom Insoles, helping halt the progression of bunions and hammertoes.
Lateral longitudinal arch (A - C)
The lateral arch is composed of the calcaneus, the cuboid and the fourth and fifth metatarsals. The most marked features of this arch are its solidity and its slight elevation.
The lateral arch is seen most frequently in people with uncommonly high arches. In a case of a high arch, FootBalance Custom Insoles help support the lateral longitudinal arch whilst balancing the foot position.
