## Overview

The Aircast Walker Brace Replacement Foam Liner with Insole is a lightweight, hand-washable foam insert designed for both left and right legs. Compatible with Aircast FP and SP Walker Boots (sold separately), it restores comfort and support for foot and ankle injuries, ensuring a secure, breathable fit that promotes natural gait and accelerates recovery.

## Description

Keep your Aircast Walker Brace / Walking Boot like new with this replacement foam liner and insole. Choose between the Aircast FP (Foam Pneumatic) and the Aircast SP (Short Pneumatic) models. This lining can be hand washed with a mild detergent; simply allow to air dry. Universal fit allows the Aircast Replacement Foam Liner with Insole to be worn on either the left or right leg. The Aircast FP and SP Walker Brace / Walking Boot (sold separately) is a removable cast that will not limit mobility required for day-to-day activities while recovering from injury. It's specifically designed to provide protection and pneumatic support for stable fractures of the foot and ankle, severe ankle sprains, soft tissue injuries, chronic conditions including plantar fasciitis, metatarsal fractures, forefoot and midfoot injuries, bunionectomies and post-operative use. The low rocker sole promotes a natural ambulation (gait) for improved mobility while the generous foot base has ample room for dressings without sacrificing comfort. The lightweight, semi-rigid shell has a pre-inflated anterior air cell and 2 adjustable Duplex air cells located at the malleoli that can be individually inflated for a total contact fit and secure support. It provides the protection and stability necessary for a healthy recovery.

Review: A Perfect Fit - Perfect replacement for my Aircast boot. Came with 3M adhesive on the heel of the insole for you to place and velcro pre-installed where needed to fit into the boot. Very happy since my old liner had seen better days and the velcro would no longer catch the fabric very well. Sad that I need to use the boot again but very glad to be able to give it a refresh.
Review: Excellant fit and quality - Excellent fit. I love it because it was taller than the original one that came with my Medical boot. No pain or irratiation from the boot staps or the top of the boot. Durable. Thank you.

## Questions & Answers

**Q: I need a replacement for my below the knee boot for my right leg.  It is old so I don't know the model.  Cn you give me dimensions for the liner?**
A: If the boot is a knee-high boot, the liner will be perfect. I had a broken foot last summer, and it was very hot where I live, so having two liners was great. I'm sorry I cannot measure it for you; it's in my cellar. I got hit by a car in April, and after 19 days in the hospital I am stuck on the first floor with a walker, learning to walk again with a new hip.

**Q: How do I the odor away?**
A: I wash mine on the gentle cycle on my washing machine and hang it up to air dry. I use disinfectant wipes to clean the hard surfaces of the boot.

**Q: Does the fp replacement liner work for the airselect model?  amazon does not seem to sell a replacement liner specifically for the airselect model.**
A: It was an exact replacement for my Airselect Standard Walker.  Look and fit is the same.

**Q: Does it come with the foam replacement that sits on top of the boot sleeve?**
A: I don't know what you mean by "on top of the boot sleeve". The footbed has a seam at the fold that bothered me so I put a Dr. Scholl's type shoe insert inside the liner to pad the bottom.

Excellent fit. I love it because it was taller than the original one that came with my Medical boot. No pain or irratiation from the boot staps or the top of the boot. Durable. Thank you.

### ⭐⭐⭐⭐⭐ Great purchase!
*by B***R on March 8, 2024*

I got put back in my boot for another 4-6 weeks and my liners Velcro had seen better days. It also kept slipping down and causing the brace to bruise my calf. So when I found this I ordered it and crossed my fingers. It did not disappoint! It is actually thicker and more comfortable than the paid that came with my brace and it fit perfectly. This time I purchased some basic velcro dots from Walmart and added them to the top sides of the brace and liner to help keep the sides from being pulled down and it has worked like a dream. Very happy with this purchase so far. I’ve had it for about a week and it is holding up perfectly.
