Has anyone ever spent the $215 or $225 on SureFit custom boot insoles? Is it worth it? I bought new Lange boots last year and they are fine. But I have a funky bone on my inner left ankle that has been bugging me this year. It sticks out further than the bone on my right ankle. So I go into SureFit in Killington this past Sunday to get that boot blown out a bit in that one area and they try selling me custom insole instead. Any one else have this issue?
