Abstract: An orthotic ankle garment is integrally knit of a body yarn, and comprises at least one compression zone incorporating elastic yarns integrated with the body yarn. A lateral fabric brace strap is integrally formed with the body yarn within the compression zone, and is adapted to extend vertically on an outside of the lower leg between the open leg end of the garment and a termination point proximate a lateral malleolus of the ankle. A medial fabric brace strap is integrally formed with the body yarn within the compression zone, and is adapted to extend vertically on an inside of the lower leg between the open leg end of the garment and a termination point proximate a medial malleolus of the ankle. The lateral and medial brace straps define vertically-disposed areas of reduced fabric stretch relative to directly adjacent areas of the compression zone.
