I want to love them, but the lip around the heel rubs the heel very hard. I have flat feet with pronation, that could be a factor. The sole is also more like plastic, so the bottom of the foot sweats a lot. This is my first pair of strapped saddles so I'm still trying to get used to how tight they have to be. However, now I understand why there are so many reviews saying they are broken. The ring on the back strap is the only weak point if you overtighten it. I've done short hikes in them and walked in them for hours with no problems or discomfort...except sweat.
