I have the 10's and I think they are crap, they wear out way too fast for what they cost and I have had the same problems with buckles as NeverSurfaced, they just dont last. IMO Sidi's are way better quality, they will be the next boot I buy. This guy even resoles Astar boots with Sidi soles because Astars are crap! http://www.factoryresole.com/
