I have a problem

The problem is with my boots or so i believe. lately when i ski i have taken 1 run and my shins have hurt so bad it hurts to barely touch. touch as in less then the force needed to type. It hurts so bad i cringe my whole body. its mainly my right shin but of course your body adjusting to the pain of my right shin effects my left shin. last time it happened was like 3 weeks ago. i skied at mt snow for a day. 2 runs in and my shins hurt so bad i couldnt stand it. i ended up just riding with nothing above my ankle buckled/ strapped so just my bottum buckles buckled. but then my feet get numb just on the first buckle on each. I have last years salomon foils if that means anything. I guess all im asking is if its something i can do with the boots or if its my shins or what. Do they make boots with a taller foot part so my feet dont get numb or what.... it would be awsome for anyhelp so i can ski again this season
