Ossur Rebound Achilles Heel Wedge Kit | Cast Boot Accessory for Achilles Rupture Rehab
The Ossur Rebound Achilles Heel Wedge Kit is the clinical standard for both functional (non-surgical) and post-surgical rehabilitation of Achilles tendon ruptures. Designed to work with walking boots, the kit provides adjustable plantar flexion angles that can be progressively modified throughout recovery — giving clinicians and patients precise control at every stage of healing.
Each kit contains 1 wedge constructed from multiple stackable layers. Layers are removed one at a time as rehabilitation progresses, gradually reducing the plantar flexion angle. Sized kits (Small, Medium, Large) include a wedge with 3 layers; the Universal kit includes a larger wedge with 5 layers.
Clinical Indications
- Full or partial Achilles tendon ruptures
- Functional rehabilitation during non-surgical treatment
- Post-surgical Achilles tendon repair recovery
- Conditions requiring immobilization in plantar flexion

What is an Achilles tendon rupture and how does a wedge kit help recovery?
An Achilles tendon rupture is a complete or partial tear of the tendon connecting the calf muscles to the heel bone. It is one of the most serious soft tissue injuries in the lower extremity. The heel wedge kit holds the foot in plantar flexion (toes pointed down) inside a walking boot, reducing tension on the healing tendon. As healing progresses, layers are removed one at a time to gradually bring the foot back to a neutral position — a process called progressive mobilization.
Will this wedge kit fit my walking boot?
Yes — the Ossur Rebound Achilles Wedge Kit is designed to fit the Ossur Rebound Short and Tall Air cast boots, and is also compatible with virtually any walking boot used for Achilles tendon treatment.
How many wedges are included, and how do the layers work?
Each kit contains 1 wedge made up of multiple stackable layers. Sized kits (Small, Medium, Large) include a wedge with 3 layers; the Universal kit includes a larger wedge with 5 layers. As rehabilitation progresses, layers are removed one at a time to gradually reduce the plantar flexion angle.
Can this be used after Achilles tendon surgery?
Yes. The kit is clinically indicated for both non-surgical (functional) and post-surgical rehabilitation of Achilles tendon rupture. Always follow your surgeon’s specific protocol for wedge removal timing.
How long does Achilles tendon recovery take in a walking boot?
Most Achilles tendon ruptures require 8–12 weeks of boot immobilization, with progressive wedge removal beginning around weeks 2–4 depending on the treatment protocol. Non-surgical protocols typically involve earlier mobilization than surgical repair. Return to full activity varies widely — most patients return to sport at 6–12 months post-injury. Your orthopedic surgeon or physical therapist will guide your specific timeline.
