Quick answer: This is the Össur Rebound Air Walker Short (Low-Top / “LT”) — a premium removable pneumatic CAM (controlled ankle motion) walking boot with an integrated air bladder for adjustable compression and swelling (edema) control. Its short, low-top design immobilizes and protects forefoot injuries, toe and metatarsal fractures, and minor ankle trauma without the bulk of a full-height boot — giving maximum lower-leg mobility and comfort. A rocker sole promotes a natural gait, ventilated panels keep it breathable, and a single-point air pump lets you fine-tune compression tool-free. Fits either the left or right foot. FSA/HSA eligible. (For above-the-ankle immobilization, see the Rebound Air Tall.)

About this product
Many patients call this an air cast boot, cast boot, or fracture boot — it’s a removable walking boot that immobilizes the foot/ankle while you heal, with pneumatic compression built in:
- Short / low-top design — lower profile than a tall walker; ideal for forefoot and toe/metatarsal fractures and soft-tissue trauma where full-height ankle immobilization isn’t needed, so you keep more lower-leg mobility.
- Integrated pneumatic air bladder — a fully integrated single-point air pump with a push-button release valve; internally linked medial and lateral bladders inflate evenly to give adjustable, even compression and help manage swelling — adjustable on the go, tool-free.
- Rocker bottom sole — engineered to promote a natural, stable gait and reduce stress on the foot.
- Breathable & comfortable — ventilated panels and moisture-wicking soft goods reduce microbial buildup; EVA construction absorbs shock at the heel; a trimmable semi-soft toe bumper adds protection against re-injury.
- Removable & closed-toe — take it off for washing, sleep, and skin checks (unlike a cast); the fully enclosed toe protects the foot.
- Fits left or right — no side selection needed.
Short vs Tall — choose the height
- Short / Low-Top (this) — lower profile; best for forefoot injuries, toe and metatarsal fractures, or when less ankle restriction is needed.
- Tall / High-Top (Rebound Air Tall) — extends above the ankle for maximum immobilization; best for ankle fractures, severe sprains, and Achilles injuries.
Sizing
Available in multiple sizes (S–XL typically) based on shoe size — check the size chart. The boot fits either foot.
| Size | Men’s US | Women’s US |
| XS | 2–4 | 3.5–5.5 |
| S | 4–7 | 5.5–8.5 |
| M | 7–10.5 | 8.5–12 |
| L | 10.5–12.5 | 12–14 |
| XL | 12.5–15 | 14–16.5 |
Fit tip: the shell is wide-set to accommodate bandaging and swelling. If you’re between sizes — or managing significant swelling or thick dressings — size up for adequate clearance. If swelling is minimal, choose the smaller size.

Frequently asked questions
What is a CAM walking boot?
A removable “controlled ankle motion” boot that immobilizes and protects the foot/ankle while you heal — an alternative to a cast that you can take off for washing and skin checks. This one adds an integrated air bladder for adjustable compression.
How do I choose my size?
By your standard US shoe size (XS: men’s 2–4 / women’s 3.5–5.5; S: 4–7 / 5.5–8.5; M: 7–10.5 / 8.5–12; L: 10.5–12.5 / 12–14; XL: 12.5–15 / 14–16.5). If you’re between sizes or have significant swelling or bandaging, size up. It fits either foot.
Short or Tall — which do I need?
The Short (low-top) is best for forefoot, toe, and metatarsal fractures or minor trauma. The Tall (high-top) extends above the ankle for ankle fractures, severe sprains, and Achilles injuries. Follow your clinician’s guidance.
How does the air pump work?
A single-point pump inflates linked medial/lateral bladders for even compression and swelling control; a push-button valve releases air — all tool-free, adjustable on the go.
Which foot does it fit?
Either — it fits the left or right foot, no side selection needed.
Is it removable?
Yes — unlike a cast, you can take it off for sleeping, washing, and skin checks (as directed by your clinician).
Do I need a prescription?
It may require a prescription as a clinical immobilization device — contact us and we can help. It’s typically FSA/HSA eligible.
Can I get it delivered in Brooklyn or shipped nationwide?
Yes — Task Supply Corp offers USPS shipping throughout the United States, plus local pickup and delivery in Brooklyn and all five boroughs of New York City.
