How do you keep your feet warm in the stand/blind?

One of the reasons I gave up deer hunting, cold feet...

I wear wool socks and lacrosse alpha burleys. An old timer told me to take a roll of toilet paper, remove the card board, and stuff it in a metal coffee can. Then soak it with rubbing alcohol and light it up. Just put the lid back on to snuff out the fire. Also, there's no smoke. So, if it's really cold and I'm hunting a box stand, I'll do that.

Make sure you have well fitting boots

Make sure you have socks that don't keep your feet too warm

If your boots are tight your feet will be cold no matter what

Muck boots and normal heavy cotton socks are all I ever need.

My feet used to freeze until I figured all this out
