This is the second pair I've bought. I have heel spurs on both feet and these shoes are soft enough on the back to not put a strain on the spurs. I use them for work and they hold up to the 8-12 hours I'm on my feet, I placed my orthotics on top of the insole so thay might be why.
The Navy color looks drab grey after washing so I don't recommend that color and I haven't washed the glossy black I have yet. I may not wash them because they can be wiped clean.
