Walking in these shoes is like walking on ice skates. I didn't realize that the bottoms were going to be slick when ordering. I have had a pair of bobs that I was looking to replace and chose this item. When it arrived there was a clear like film over the bottoms which I didn't really think anything about. I tried them on and stepped on the tile floor almost falling on my butt. No amount of wearing would make the tread not slick in my opinion.
