I work in the food service industry and have searched high and low for a comfortable non-slip shoe that my restaurant would approve.  After trying several different pairs of work shoes from different manufacturers and being disappointed with each one, I had almost given up.  As it was, I had spent $25-$68 per pair, with each one being more expensive than the last.  Then one day I was wearing an old pair of Crocs around the house and suddenly wondered if they made food industry grade shoes.  After a quick search online, I found these for less than $30.  This is the first time that I can work a full shift and have NO foot or leg pain.  I am so grateful.  And after working in them for 8-9 hours at a time for the past month, they are holding together perfectly.

The only negative I have found is that the non-slip bottoms do not provide as much traction on wet surfaces as some of my other shoes.  So I do have to be a bit more careful.  Small price to pay for painless nights!

Note: They do not come in half-sizes, so they suggest you order the lower end of your half-size.  I did this and they can be a bit snug at first, but within a few minutes of walking, they warm up and stretch.  No problems.
