The AIrcast SP Walker is a short pneumatic style walking boot that's designed to promote natural ambulation for improved mobility. It provides full-shell support and compression for patients with foot & ankle injuries. The SP Walker (short pneumatic) is suited for individuals with a shorter leg length/ calf circumference that require a short height walker for injury immobilization.  The walking brace design provides additional containment of the foot for proper immobilization of sprains and fracture injuries. Inflatable aircells on each side of the ankle, along with a pre-inflated cell over the forefoot provide customized support and reduce swelling for faster healing.

The SP Walker features a low rocker bottom that makes ambulation safe and comfortable on all surfaces.   The Aircast SP Walker is used for recovery from mild to moderate ankle sprains, rehabilitation following bunionectomies, forefoot soft tissue injuries, metatarsal fractures and more.

Aircast SP Walker™ Features:

  • Low rocker sole offers enhanced comfort and promotes natural ambulation.
  • Wider foot base provides ample room for dressings.
  • Improved ergonomic design for ease-of-use and increased compliance.
  • Engineered for patient comfort while providing superior injury protection and support.
  • Semi-rigid shell has a pre-inflated anterior aircell and two adjustable aircells located at the malleoli (medial and lateral ankle bones) that can be individually inflated using the hand bulb (included) for a "total contact" fit and secure support.
  • Because of the walker's adjustability, changes in limb dimension due to swelling can be adjusted for throughout the healing process while still maintaining stability and immobilization per the physician's protocol.
  • Improved ergonomic design for ease-of-use and increased compliance.
  • Available in five sizes to fit every size foot - please read our sizing chart tab above for complete sizing guidelines.
  • Fits both right or left sides.

good ankle air cast boot
This ankle air cast boot helped get rid of my swelling and helped me walk better after a sprained my ankle three weeks ago. It didn't affect my mobility either.

Inappropriate review? 
Doctor approved - good with it.
It's doctor approved so I'm good with it. I prefer the 2 straps on the SP to the 3 straps on the taller versions. That is why I choose this particular boot. Don't always use the air pump that came with it. My hips tend to hurt from walking around in it all day long so I also got the Evenup to go along with it.

One of the better walking boots out there...
Some boots offer only medial and lateral support but this provides support all the way around the ankle which my surgeon wanted me to have.

Air leaked but got it replaced
The air leaked on my first one - had to keep pumping it back up. Called and got a new replacement overnighted without issues. Can't beat this air cast boot cost!

Worked great for me
Worked great for me, not to mention it also turned out to be $200 cheaper than my insurance company wanted me to pay out of my own pocket at the ortho.

Ran too small
Ran too short for my shoe size - toes were hanging off the end. Had to exchange for the next larger size.
