Footwear is a "trial and error" exercise for most with CRPS affecting that area. And I've tried plenty!

As I really need the support of an athletic shoe because of other foot problems, but want minimum pressure on the foot from the shoe, I have had the best luck with New Balance running shoes; specifically the 883 model, which is designed with a roomy toe box and forefoot area.

The running shoes have a mesh over a good part of the top of the foot, rather than leather which is not as forgiving.

I also went from a regular shoe width to a 2E in width. The extra width giving additional room to the foot.

This shoe has really helped me a lot in pain reduction and in attempting to keep a good mechanical "gait" while walking.

Good luck.......
