Although good footbeds are the best solution, you can slip wedges under your heels to correct for a foot that rolls to the inside (pronation) or outside (supination).
Correcting pronation will make the foot seem shorter and narrower for less pinching in the boot.
It will also aid in edging, slow down rotation causing shin bite, and cut down on arch cramps.
They can also be used for other wedging, such as around an ankle bone, etc.
Made of high grade flexible PVC, cushions shock but does not compress.
Will not absorb moisture.

I have used these to help our instructor staff become more 'centered' in their stance. One report stated that she "never felt so comfortable in ski boots - ever." Size varies with individual and boot shell.
