The area where your heel rests is really strange, I was definitely not a fan of it. It squeaked terribly, and the way the shoelaces rest makes it feel like they are not secure on your feet. I didn't feel comfortable walking around in them as they felt that they would fall off. Also, the rubber front part is very small, I believed it would have been more of a cap, or provided at least a little protection on the top, but it really is more of a bumper if anything.
