I have posted this numerous times but I'll post it again...

Cold feet, for me at least, is caused by sweaty feet. I don't hunt much, but I do fish, all winter long. I've been fishing in temps as low as 19 degrees. I wear my fuzzy crocs, and cotton ankle socks to the boat ramp. Once I get there, I take the cotton socks off, and let my feet air dry. Then I put on wool socks and fish without my feet ever getting cold. The crocs let most of the sweat evaporate out the holes on the top. I don't have any fancy wool socks, just cheap wool blends from various stores. When I do deer hunt, I do the same, except with Muck boots.

If you have chronic cold feet, sweating in your boots could very well be the issue. Damp feet are cold feet. All you have to do to test this, is to take one boot and sock off, outside, with a slight breeze blowing. If your foot is damp from sweat, you'll know quickly with the breeze blowing.

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land. 2 Chronicles 7:14
