Product Questions

What's the difference between this and the regular airstirrup brace?
Question by: AJ on Mar 26, 2010, 1:58 PM
The Aircast Air-Stirrup Universe more of a one size fits all Ankle Brace. It is not made to specifically fit left vs right, or differing sizes.

Both ankle braces will address Acute injuries of the ankle, and Severe Chronic Instability.

The Aircast Air-Stirrup Ankle Brace is anatomically designed to apply to the Left or Right foot. In addiction the Aircast Air-Stirrup Ankle Brace comes in differing lengths of size, depending on your needs.

Due to the more customized fit that you would get from the Aircast Air-Stirrup Ankle Brace you'll get greater and more effective compression on the joint line, which will reduce overall swelling more effectively.

As with all size and left right and size specific ankle braces vs a universal brace, the Aircast Air-Stirrup Ankle Brace is going to be very much more comfortable to wear due to the anatomic design.

Can this be worn to help heal and support a torn achilles tendon?
Question by: Andrew Vorkas on Jan 8, 2015, 12:19 PM
The aircast Air stirrup will only provide ankle stability. I would suggest the Aircast air Heel. the brace has a air pad in the heel and around the back where the Achillies is located. Every time you step down the air is pushed to your achillies to give it some support.

Can you wear the air stirrup ankle brace while playing sports to protect your ankle and keep it stable or would this cause more injury?
Question by: Lesli on Jul 7, 2011, 9:23 AM
No the air stirrup brace should not be used to play sports. it is not made to endure the impact of sports. I would suggest looking into either the Airsport, or the A60.

For a sprained ankle ( 2 or 3 severity) what is the difference from using this and a walking boot?
Question by: Sarah on Aug 14, 2016, 9:55 AM
A walking boot will prevent all range of motion, which the air-stirrup won’t. We would recommend you consult with your doctor first.
