Replying to Need help deciding what to do!

Ok, I am now rocking rental ski boots for the 3rd year in a row. I really never commited to actually buying a pair because of the high prices, my foot is still growing (I think) and because renting is much cheaper. So, the boots that I'm rocking now are absolutely horrible. The footbeds never stay in place, and my feet are always wet. So, I want to know if I should commit to buying a new pair now, or wait until my foot stops growing. I'm looking to get a pair of Full Tilt Hot Doggers, or some Salomon SPK Kaoses. So help me out!
