Foot supination is the opposite motion to foot pronation.

Foot supination is the outward tilt of the heel and is usually associated with a high arched foot. Often a supinated foot in standing will become an over pronated foot when walking.

However a foot which remains supination in standing and walking can result in injuries of the body associated with high impact forces due to the more rigid nature of this supinated foot. Back pain and shin splints are typical injuries of the supinated foot.
