I'm a cook and a butcher so, as you know, I'm on my feet all day, every day, in a dangerous environment. I started wearing only sketchers to work about 10 years ago and I have no regrets at all. My last pair of Sketchers ended up falling apart at work, so I looked to Revain for a new pair. I found them and decided to give it a try. They arrived on time and the packaging was good enough for me. Of course I took them out of the box, put them on and got to work. This is how I wear my shoes. They fit perfectly and are true to size. I've had them for a week now and honestly I feel like I've had them for years. There was NO "break-in period" at all. These shoes were very comfortable from the moment I put them on and didn't cause me any discomfort. And it is really non-slip shoes. I am very happy with these shoes and will definitely buy them again. In fact, they look so pretty that I plan to buy another pair and use them as dress shoes. I highly recommend these shoes.
