Replying to I have a pretty bad boot problem. help = +karma

so i had the foil boot for the past year and it was my first season and my first pair of boots i bought them online having no idea at all about choosing boots. so now i realize there is more to it than just picking out what sounds the best so now i have a major problem the when i tighten the boots to the tightest i can get them w/o cutting off my circulation my heel slips up and down really far. and the problem is i live in nebraska so there is one place that sells boots and the fitters are clueless.. what do i do?
