So I have used boots that are a little small but im going to suck it up for the rest of the season and buy spks next year. So they were pretty painful when i first was skiing on them, but i broke them in a little more and there getting better. But i still have rubbing in the heels, theres a blister in the back. Its mainly when i butter but still is annoying. Also in my pinkie toes both kinda burn when i take them out. I think its so tight that theres no blood cirulation in my toes. Any suggestions?
