Air-Stirrup Ankle Braces are constructed with molded sides to approximate the ankle and fit comfortably in the shoe. Pre-inflated, adjustable air cells line the interior, conform to the individual, and gently compress swollen tissue. When worn with a laced shoe the brace effectively limits inversion/eversion but permits dorsi and plantar flexion. The standard model is intended for acute injuries in all but the smaller patients, the training brace for chronic instability and prophylactic athletic support and the small brace for acute and chronic injuries in patients 5'2" and smaller. All braces come in left and right models.
