Replying to Toe Bang?

I'm not even sure what to call it so I will just call it toe bang. Anyways, I am trying to get your opinion on what is going on in my boots, well more specifically my right boot. Every time I go skiing and actually ski hard all day(never leave the terrain park) I always end up with a sore big toe. What I am wondering is should I get new boots or a new liner? I'm not sure if this is a Full Tilt thing or what but for my toes sake I really need to figure something out. +K for all the help! Thanks.
