Ive had some pretty nasty situations on a dirt track where I'm glad to have my Tech 7's, Ive had my left foot run over, my ankle smashed in between 2 bikes, my bike land directly on my foot after a high side, and got on the bike after every time. Kinda cheap, comfy, light, Im on my 3rd pair of Tech 7's right now and its because of getting them burned by a down pipe with no heal shield. I tried on 10's in the store and they didn't seem to fit the way that 7's do. Im not too much of a fan of the inner bootie thing, just make sure they are on good & tight! Cant go wrong with A stars.
