The Aircast Air-Stirrup Ankle Brace is commonly worn immediately after an ankle injury and throughout recovery. It's intended to prevent or treat acute ankle injuries, chronic instability, post-operative use and ankle sprains grade I, II, and III.
It features semi-rigid, anatomically designed shells which help stabilize and protect the ankle. These shells are lined with patented Duplex air cells that support and produce graduated compression to enhance circulation and reduce swelling and edema. The air cells are pre-inflated distal and graduated compression during ambulation.
This Aircast ankle brace has a low-profile structure, allowing for minimal bulk while wearing shoes. The Aircast Air-Stirrup Ankle Support Brace resists inversion more than taping, yet normal flexion is virtually unrestricted.

Good stirrup. My Aircast helps
I have been using this stirrup for 7 years because of a tendonitis injury in my ankle. The stirrup fits inside most of my shoes rather easily and I use it every day. It molds to my bony ankle and keeps it from twisting which causes me to have pain without. This Aircast stirrup is a godsend.

perfect for my son's ankle sprain
I just got this stirrup brace for my son's ankle sprain. It's the same as the one my physician friend recommended. It arrived in a couple of days so shipping was very fast.

Daughter sprained her ankle
My daughter sprained her ankle and found this air-stirrup for her ankle. I received it the next day - the fast delivery is appreciated!
Correct product
Easily found the correct product. The product arrived in a timely manner. The Air-Stirrup matched perfectly to what I ordered. Thank you and look forward to using your company in the future for my needs.
My left ankle is well supported and healing.
Over several months of abusing my left ankle while doing calisthenics and household chores, I realized something was wrong. It became more and more painful, and I knew my 70+ ankle needed more respect. I consulted my doctor, and he ordered an x-ray, then a MRI. Though nothing was broken, he said I should get an ankle stirrup. I bought this one online and am very pleased with it.
pain relief and ankle support
I have a swollen, painful ankle due to an arthritic condition affecting the tendons and ligaments. It is well made and anatomically correct for the right ankle. It is usually prescribed for ankle sprains. It has an air chamber and a gel chamber and the heel spacer is adjustable with velcro to size any width foot.
Ankle feels more supported with this.
The brace gives me great support.
Fast delivery was affordable
The air stirrup ankle support helped my ankle sprain a lot. Glad you ship to Canada affordably.
Not comfortable enough
Wasn't comfortable inside my shoe - returned it.
Five Stars
I played basketball with these on both ankles, and they worked well to protect my ankle and my achilles. Very pleased.
