I'm so sorry to write this but I wore them to school once, I teach, I'm up all day too the legs. I teach computer science. but the seams on the sides above where it is sewn are beginning to unravel. I took them to our local shoe store and they fixed them. Then I started wearing them again and damn the seams on the other shoes came undone so now I don't wear them at all. I've bought a few of these (well, several pairs) and worn them out. But for some odd reason they weren't as comfortable as the others and falling apart so easily isn't what these shoes were designed for. But I called the company and they said it shouldn't have happened. In any case, I'll have to reconsider another order. Sorry for this review but I have to tell the truth.
