Ossur Formfit Walker Air – Standard Height Walking Boot

The standard-height walking boot is designed to immobilize the foot and ankle when motion restriction is required. It may be recommended for Grade 2 and Grade 3 ankle sprains, stable fractures, soft-tissue injuries, trauma, post-operative recovery and rehabilitation. It should be used under the direction of a qualified healthcare professional.

This product is the standard-height or tall version. It extends above the ankle to provide additional ankle and lower-leg immobilization. The low-top version is a separate product.

The Walker Air includes an integrated pneumatic chamber that allows compression around the lower leg and ankle to be adjusted. The non-air version provides immobilization without an inflatable air system.

Select the boot according to regular men’s or women’s shoe size. The heel should sit completely against the back of the walker and the toes should remain supported by the footbed. Swelling, bandages and foot width may affect the fit, so contact The Physio Store when a shoe size falls near a sizing boundary.

Yes. The Össur Formfit Walker Air Standard has a universal design and can be fitted to either the left or right foot.

First position the heel fully inside the boot, close the liner and fasten the straps. Turn the valve clockwise and press the air bladder repeatedly until the boot feels snug and supportive. Do not overinflate it.

Turn the valve counterclockwise to reduce the air pressure. Deflate the chamber if the boot feels too tight and before removing the boot.

The boot should feel snug and supportive without causing pain, numbness, tingling, skin discolouration or circulation changes. Release air and loosen the straps if excessive pressure develops. Contact a healthcare professional if discomfort continues.

The rocker sole is designed to support a stable walking pattern, but you should walk or place weight through the injured foot only when authorized by your treating healthcare professional. Crutches, a walker or another mobility aid may still be required.

Follow the specific wearing schedule provided by your physician, surgeon or therapist. The manufacturer advises that the device should not be removed unless instructed by a healthcare professional.

Remove the liner and hand wash it with mild detergent. Rinse it thoroughly and allow it to air dry. Do not machine wash, tumble dry, iron, bleach or use fabric softener.

Wipe the plastic components with a damp cloth and mild soap. Allow the walker to dry before reinstalling the liner.

Regular healthcare supervision is recommended for people with peripheral vascular disease, neuropathy, reduced sensation, diabetes-related nerve changes or sensitive skin. The device should not be applied to someone who cannot communicate discomfort.

Release air, loosen the straps and check the skin and circulation. Stop using the boot and contact a healthcare professional if pain, numbness, discolouration, excessive pressure, irritation or another unusual reaction continues.

Yes. The air chamber may expand at higher altitude. Recheck the fit and release enough air to maintain comfortable compression when travelling to a significantly higher elevation.

No. The Formfit Walker Air is intended for repeated use by one patient and should not be shared.
