Replying to Help with my boots

I picked up a pair of lange vector x's at the local ski swap for 90 bucks and i was just riding them in fernie for 4 days staright and the boot slowly got bigger. I think the padding started to srink and im flopping around in the boot a bit. It hurts alot. When i lean back in my boot theres like an inch from my shin to the padding at the very top. should i sell these boots. Its the worst pain ever on the bottom of my shin. should i wear poofy socks and suck it up?
