has anyone tried the spk boots outside of the park yet? i've been looking at salomon boots since my foot fits in them the best, but i can't decide if i should get the foils, guns, or spks. i plan on doing mostly park but i'm going to do some skiing out of the park and back country. it looks like the spk boot wasn't really designed to go out of the park so i'm worried it might be terrible as soon as i get into powder even though i'm not going to be doing it often, because it isn't in a skier stance position. which do you guys think i should get?
