Overview
Aircast builds the AirHeel around two linked air cells, one under the arch and one behind the Achilles tendon. Each step squeezes air from the arch cell into the heel cell, giving pulsing compression inside a slip-on spandex sleeve with a strap.
Moving compression is the reason to choose it: walking itself drives the air back and forth, easing load on the plantar fascia and the Achilles without any pump. Support is limited to compression and side stabilizers, so an unstable ankle after a sprain needs a stiffer brace.
Who it's for
Heel pain from an irritated plantar fascia or a strained Achilles during daily walking and running is the target situation. Someone needing ankle immobilization after an injury should look at a firmer design.
Pros and cons
- Compression pulses with every step

- Compression only, no rigid ankle support
- Single medium size in this listing
Performance notes
Relief comes from air moving between the two cells as the foot loads and unloads, so it works mainly while walking and does little at rest. Strap snugness decides how firmly the cells press on the heel and tendon. The stabilizers add side to side feedback without holding the joint rigid.

Frequently asked questions
How do I put on and adjust the Aircast AirHeel?
Slip it on like a sock, then adjust the Velcro strap until it feels snug. The same brace works on either foot.
Will the Aircast AirHeel hold up to running and jumping?
Aircast says the air cells were tested with 1,000 lbs of pressure so they withstand running, jumping, landing and other high impact activity.
Does the AirHeel brace fit inside shoes?
Yes. The low profile, breathable build is designed to go inside most shoes without adding bulk.
Is the Aircast AirHeel a rigid ankle brace?
No. It is a compression sleeve with air cells and side stabilizers, aimed at heel and Achilles pain rather than immobilizing a sprained joint.
