I had the and they gave me blisters every time I ran. I upgraded to the Gel Kayano and I have NO blisters. They are a tiny bit heavier than the but still fairly light for a shoe. VERY COMFORTABLE and the built in support is awesome!
The Shox NZ is built for those who love the ride and feel of Shox but want a faster, lighter alternative. A simple one-piece sleeve inside the upper gives this running shoe a dynamic fit like no other. The upper is made of sythetic/leather.
