Im a park skiier and i do a bit of powder when i go to the mountains. Right now i have these crap boots and i get really bad shinbang, i was looking at full tilts, but are there any other options that might not be as pricey?
That a mighty fine setup right there! I'm thinking of that for myself for next season.
To OP, go to a quality shop, talk to an experienced boot fitter/tech, tell them what you are looking for in a boot, and then try on everything. You may still need some custom work (ie stretching/grinding) but if you start off with a boot that is a close to fitting your foot as possible, it will make things a lot easier for you, your feet, and the person helping you.
