Frequently Asked Questions
Will this liner fit my Rebound Air Tall boot?
No. This liner is designed exclusively for the Rebound Air Short Low Top cast boot. The Short and Tall boots use different liner dimensions and are not interchangeable. If you have the Rebound Air Tall High Top boot, you need the Rebound Air Tall Replacement Liner. If you are unsure which boot you have, check the label on the boot shell or contact your clinician.
How do I know which size liner to order?
Order the same size as your Rebound Air Short boot. Sizes are based on calf circumference measured at the widest point of the calf: X-Small = up to 12" (30.5 cm), Small = 12"–14" (30.5–35.6 cm), Medium = 14"–16" (35.6–40.6 cm), Large = 16"–18" (40.6–45.7 cm), X-Large = 18"+ (45.7+ cm). If you are between sizes, size up for a more comfortable fit.
When should I replace my CAM boot liner?
You should replace your CAM boot liner when it becomes visibly soiled, develops an odor that washing cannot eliminate, shows signs of compression or flattening that reduces cushioning, or if your clinician recommends it for hygiene reasons during a long-term treatment protocol. For patients wearing a fracture boot for 6–12 weeks or longer — such as those recovering from a Jones fracture, stress fracture, or Lisfranc injury — replacing the liner midway through treatment is common practice to maintain comfort and reduce infection risk.
Can I wash the existing liner instead of replacing it?
Ossur recommends hand washing the liner with mild soap and allowing it to air dry completely before reinserting it into the boot. However, repeated washing can degrade the foam padding and moisture-wicking properties over time. If the liner has lost its shape, cushioning, or odor-control ability after washing, replacement is the better option. A fresh liner also reduces the risk of skin irritation and maceration, which is particularly important for patients with diabetes or compromised circulation.
Is this a genuine Ossur part, and is it FSA/HSA eligible?
Yes — OrthoTape.com is an authorized Ossur dealer and carries only genuine OEM replacement liners sourced directly from Ossur. This replacement liner is generally eligible for reimbursement through Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) as a qualified medical expense.
