There’s no simple yes or no here. Ask your provider if you need special shoes that can give your feet more room.
Whether special shoes are needed depends on the shape of your foot, the feeling in it, and what your foot has already been through.
What is clear is that the device worn during healing and the shoes worn afterward are two different things. Special shoes, a brace or a special cast, and a wheelchair or crutches, take the pressure off the ulcer area. You may need them until the ulcer has healed. Those are about the wound.
Everyday foot care is different. It applies to anyone with diabetes, and it does not stop when a wound closes. Wear shoes at all times to protect your feet from injury. Check the inside of your shoes for stones, nails or rough areas before putting them on. When you buy shoes, choose ones that are comfortable and fit well. Never buy shoes that are tight, not even if you think they will stretch.
Fit matters more for you than it does for most people. You may not feel pressure from shoes that do not fit well, and blisters and sores can develop when your foot presses against your shoe.
Having had an ulcer changes how closely your foot is watched afterward. If you have had foot ulcers before, see your provider every 3 to 6 months.
If you get new shoes, break them in slowly. Wear them 1 or 2 hours a day for the first 1 or 2 weeks. Change your broken-in shoes after 5 hours during the day to change the pressure points on your feet.
