I have the same problem...my feet, just my toes really, always get numbing cold. No matter what I do. I try looseing everything...tightening it...different socks...different boots...deodorant on my feet (yea thats supposed to work, no its doesn't)...Literally, I tried everything. My problem is not that my feet are uncomfortable in my boot, they are just cold.
Any suggestions for me, for us, anyone....?
