What is Supination?

Supination – or under-pronation – occurs when feet roll outwards, placing weight on the outside of the foot.

Supination is a rare occurrence as less than 10 percent of people have the condition and is usually found in people with high arches, often called a "cavus" foot.

People who supinate may experience an outward rotation of the knee and the pelvis may tilt back. The supinated foot is also a tighter, stiffer foot that doesn't flex and bend to accommodate variations in terrain. The poor absorption of shock and lack of flexibility cause biomechnical disorders, which lead to various problems throughout the body.

Similar to pronation, people with higher levels of supination may experience pain in the feet, knees, hips, back, shoulder and neck. Inversion ankle sprains, heel spurs, hammer toes and stress fractures are common in people who supinate. 

Stabilizing Orthotics may help relieve pain caused by supination.

Supinators have a higher medial arch resulting in more weight being placed on the outer edge of the foot. Stabilizing Orthotics are recommended for people who supinate.
