Since 1978, the Aircast Air-Stirrup Ankle Brace has been the "standard of care" for the functional management of ankle injuries and has been cited in over 100 medical journals for its superior performance in helping to heal ankle injuries. Each Aircast Ankle Brace features anatomically designed shells lined with the patented Duplex™ aircell system. This exclusive system incorporates two pre-inflated overlapping aircells, distal and proximal, that provide support and produce graduated compression during ambulation. The compression promotes efficient edema reduction in addition to helping accelerate rehabilitation. All Air-Stirrup Ankle Braces (except for the pediatric model) come with a patient guide providing information on brace application and optional rehabilitation exercises. The Standard (Large), Training (Medium), and Small size Ankle Brace is available individually or as part of an Ankle Sprain Care Kit™. The Pediatric Ankle Brace is designed for children 2 to 6 years of age and is ideal for ankle stabilization in hemophilia patients. Extra long straps are available "” contact Customer Service for more information.
