Ideal For

This brace is well suited for patients recovering from acute ankle sprains or ligament injuries who need reliable inversion control during the early stages of rehabilitation and return to activity. It is a practical choice for individuals managing chronic ankle instability who require consistent lateral support during daily activities, work, or sport without the bulk of a rigid cast or walking boot. Orthopedic and sports medicine clinicians will find it a dependable option for post-fracture support during the ambulatory phase of recovery. Athletes and active individuals who have experienced repeated ankle rollovers and need a clinically proven brace to reduce re-injury risk during training and competition will benefit from the Air-Stirrup's proven inversion resistance and comfortable anatomical fit.

Frequently Asked Questions

What conditions is the Air-Stirrup indicated for?
The Aircast Air-Stirrup is indicated for the treatment and support of acute ankle sprains, stable ankle fractures during the ambulatory phase of recovery, and chronic ankle instability. It is widely used in clinical settings as a first-line brace for Grade I and Grade II ankle sprains and is often recommended as an alternative to casting for appropriate fracture cases. Consult your healthcare provider to confirm suitability for your specific condition.

How does the Air-Stirrup control inversion without limiting flexion?
The brace uses rigid anatomically contoured shells positioned on the medial and lateral sides of the ankle. These shells resist the inward rolling motion (inversion) that causes most ankle sprains, while the open front and back of the brace allow the ankle to flex and extend naturally during walking and activity. This design supports safe, functional movement during recovery rather than immobilizing the joint.

Will this fit inside my shoe?
Yes. The Air-Stirrup is designed with a low-profile, minimum-bulk construction that fits inside most standard athletic and casual footwear. You may find it more comfortable to wear a shoe that is a half size larger than usual to accommodate the brace, particularly if you are wearing it over a sock.

How do I care for the Air-Stirrup brace?
Wipe the shells clean with a damp cloth and mild soap as needed. If the brace includes removable liners or padding, these can typically be hand washed in cool water and air dried. Do not machine wash or expose to high heat, which can warp the plastic shells or degrade the padding materials.
