Abstract
Abstract An ankle support is provided with an underliner having multi-directional stretch which fits over the wearer's foot in the manner of a sock and extends to a point above the ankle. A non-stretch lateral strap is secured to the underliner at a point below the ankle joint and extends upwardly to the top of the underliner, where it is inelastically secured, with provision being made for adjustment of its tension. A non-stretch medial strap is inelastically connected to the lateral strap therebelow. The medial strap extends underneath the foot and up the opposite side thereof, and it is inelastically secured to the leg near the top of the underliner, with provision being made for adjustment of its tension. The medial strap thereby supports the wearer's arch and, in combination with the lateral strap, supports the ligaments of the ankle joint and provides a "heel lock", to limit and balance the lateral movement of the ankle joint.
