The shoes perform well on trail, especially rocks as advertised. Because of the sticky rubber, they squeak on any sort of hard floor (not an issue if you buy them for running). The gaiters are short, but they work for scree, snow, and mud. The gaiters can be a little troublesome to put on and you can't quite tie the laces with the gaiters already attached. I like them better than my previous pair of North Face XCR's.
