Jim:  a home brew version might be what Intuition Liners recommends for home heat molding their liners:  a stocking or sock filled with rice, put in the microwave, then inserted into the liner to warm it up.

You will not want to heat the sock as hot as they recommend, for risk of damaging your liners, so a shorter time in the microwave would be in order. 

You can also get similar results by using cherry pits or flax seed.  I have seen several heat packs filled with these -- my wife uses one filled with flax; works great for a sore neck or back. 

Fill a couple of old ski socks, and you'd have your own boot heaters for less than $2.  Let us know if you try it.
