Overall these shoes do what they are intended to. They start out a little stiffer than the 955 but in return appear to offer a little more support. Right out of the box they slipped a bit on the back of my feet but that appears to have improved with the breaking in process. The main issue I had with the 955's was premature heal wear. These are supposedly made tougher to improve on this and time will tell. I've had the shoes about a month and I use them to walk about 3 miles a day on a paved trail. They are serving the purpose quite well.
