I've had a pair of these for about a year. They took alot a fair bit of breaking in but, once done they're very comfortable. I have worn them on the GS but, generally keep them for trail riding as they aren't really suitable walking around when you get to where your going. If you do get some it's well worth buying spare straps as I've broken three so far. The only other problem is the plastic shin guard which melted on the 'zaust when I got trapped under the XR. Otherwise there easily the best MX/trail riding boot I've had and would definately buy another pair.
