Don't think mine are anything special, Irish Setter boots and Gander Mtn brand wool socks. More than likely my body is just more accustom cold weather. Could also be that you have to warm boots and your feet are sweating a little. Also make sure the soles of the boot have good insulation. Some don't and the cold comes right through the soles to your feet. Also make sure you dry your boots at night. Sent from my iPhone using Tapatalk
I love mine. Even wear them in my waders while duck hunting. The key is to turn them on long enough to warm your feet and then turn them off. Remote makes this easy.
