boots that fit your foot, don't let anyone else talk you into a boot that has worst fit but is more park oriented....
i'm riding technica diablos, a mediocre racing boot and i just love those things, i can put a bolt in the back to give it a very stiff flex for charging, and i can remove the bolt and get a ridiculous soft flex for jibbing....
just go try a lot of boots and get the ones that feel like you could wear em all day, you wont regret your choice....
