Replying to Painful shins

I have Salomon Kreation boots and am an all mountain skier

Whenever I ski for any period of time I start to get very painful shins around the top of my boots. Usually just on my left leg. This is especially painful if I land a jump leaning back a bit or if I am skiing over uneve ground so it throws me off balanace a bit. It feels as though my shin bone is bending around my boot.

I was wondering whether anyone knows what the problem is and whether there is anything I can do about it. It feels as though if I had a boot which stopped further up my shins nearer my knees it would stop it hurting.

cheers
