Product Questions

My ortho prescribed a walking cast for my Achilles tendonosis to allow it to rest and hoppefully repair - I did not tolerate a hard cast and am now considering your Donjoy Maxtrax ROM Air Walker. I wear a 10 Wide shoe.
Will this be a suitable stabilization for my achilles tendon?
Question by: Thomas on Aug 21, 2010, 11:27 AM
Yes, the DonJoy Maxtrax ROM Air Walker is the recommended brace to wear to stabilize and support the Achilles Tendon after injury or post-op. The Maxtrax Walkers are designed to accommodate a wide foot.

I will shortly have ankle fusion and have been told by physio there is a support boot with a little pump which secures the ankle more firmly. Is there one of these on sale here?? Thanks

Hello April,

It sounds like you are looking for the Aircast SP Walking Brace https://www.donjoystore.com/aircast-sp-walking-brace-3

There is a small bulb that inflates the brace to reduce gapping.

do I need a tool to change the range of motion on the ankle hinge?
Question by: jim on Jun 25, 2013, 5:46 AM
Hello Jim,

The hinge itself has a pin that can be removed to adjust the range of motion. No tool is needed.

Thanks for contacting Donjoy.

Do you have a replacement pump for the Don Joy Walker .the hose broke off the pump.
Question by: Tina on May 4, 2016, 1:13 AM
The air bladder is located in the liner of the Max Trax walking boots so you will need to purchase a new liner if the hose came out of the currect liner. The liner can be purchased direct from DJO Global by calling 800-336-6569
