Important considerations
- Do not walk without the cast shoe if your surgeon required protected ambulation.
- Stop if you develop new pressure spots, numbness, or foul odor from the cast area.
- Avoid uneven terrain until your care team clears more active walking.
- Follow all weight-bearing restrictions regardless of footwear.
How to use
- Open the shoe wide and slide your cast or boot in without forcing a tight fit.
- Secure straps or Velcro so the shoe stays on but does not squeeze the cast edges.
- Stand and take a few test steps on level ground before longer walks.
- Check that the sole is intact and provides even contact with the floor.
- Remove the shoe when resting if your care team allows, to inspect skin at cast edges.
- Replace or adjust if the cast thickness changes after a cast swap.
Tips & tricks
- Keep the shoe dry; use a cast shower cover for bathing if prescribed.
- Trim loose strap ends so they do not catch while walking.
- Wear the shoe on both feet only if your therapist recommends limb-length balancing.
- Inspect tread regularly for wear on the non-injured side if used as a pair.
Good to know
- Cast shoes help shield the bottom of a cast from dirt and damage.
- They can improve traction compared with walking on a smooth cast surface.
- Your team will tell you when you can transition out of the cast and shoe.
Frequently asked questions
Do I need a cast shoe for a walking boot too?▾
