I love these shoes. A little stiff around the ankle when I am walking but I don't feel it at all when I run.  Changed from a 5 star and here are my reasons:   Ok so here it is a little over a week later and I am going to be buying new shoes. For a short run of 3 miles or so they were fine but anything over that and they hurt my legs, feet, knees and I started having hip and quad pain that I have never had before. I put several miles in these shoes and they are still stif as a board! I will be buying On's again but am going back to the Cloudsurfer. Those have been the only shoe I have ever run pain free in and after spending well over $150 on these shoes I wish I had stuck with the Cloudsurfers.
