Replying to Foil vs. spk

im talkin boots here. i have salomon foils which i know are a good boot, but i have oddly shaped feet and the boots dont perform that well for me. my freind is starting skiing and will buy these boots in which case ill have enough money to get spk boots (or some other boot). i keep it simple and only do park and powder. will the spk boots be able to perform for both these types of skiing, or should i get my foils adjusted by a professional, or get a different boot altogether? advice please!
