Tried them upon receiving. Seemed fine. Wore them to walk down the street to the store. It was a bit warmer. First thing I noticed was the right shoe was way tighter than the left and by the time I returned by ankles and right middle toe had been cut up by these things. I also felt like my 4th toe was going to pop through the slats at any minute. Bummed, wanted to like but they just caused pain. I think a size up would have caused too much space in the back and made the cuts worse. If they fit, would have liked them more, but they still do feel and look cheaper than desired. To the trash these go!
