This shoe is way too expensive not to be comfortable. They hurt my toes across the top and bottom. I bought them because I was having trouble walking on the treadmill and it did help me there. I have nerve damage in my right ear which throws off my balance. This shoe does a fair job of keeping me straight and centered I just wish they didn't hurt my feet. I'm not sure what I'm going to do with them. I have other NB and they're just fine :((
