This stirrup ankle brace has a single bladder with three regulated communicative chambers. Its one-of-a-kind design utilizes the fit of low profile pneumatics to dramatically increase stability without the rolling and swaying experienced in other stirrups. The "slow rebound" air delivery design reduces bottoming out. The air bladder is enclosed and protected to prevent the air chambers from being punctured. The Airform pad captures and provides a continuous smooth interface with the surface anatomy.
