The built-in air bladder contains air chambers that can be inflated or deflated for a customized fit or to accommodates changes in swelling. The bladder and pump are built right into the liner for easy adjustments on the go -- no pump attachments required! The inflated air bladder gives a massaging effect as patient walks. The soft, breathable liner wicks moisture away from the skin. Also features criss-cross ankle straps for stability and a non-slip rocker bottom. Available in low or high height. Fits right or left. Color: Black/Gray. HCPCS Code: L4360
