Össur Formfit Air Short Low-Top Replacement Liner – CAM Walker Boot Insert
Replace the worn or soiled liner in your Össur Formfit Air Short CAM walking boot with a genuine OEM replacement. This is the official replacement liner insert designed for the Formfit Air Short (Low-Top) boot — featuring the same breathable, seamless liner with integrated pneumatic air bladder that came with your boot.
⚠️ Important: Match Your Boot Before Ordering
This liner is designed for the Össur Formfit Air Short (Low-Top) boot only. It is not compatible with the Tall/High-Top version or the Rebound Air line. Check your boot model before ordering.
Your boot model is printed on the label inside the boot shell. If you have a Formfit Air Tall boot, see the Tall Replacement Liner instead.
