Replying to Cold Toes, Need Boot Heaters

Im over it. im done with cold toes every damn day. Its not my boots i've have 7 different boots in the past 4 years. its not the size or brand ive had many different brands and bot lasts, and boot fitters fitting boots. Ive tried thicker socks, thinner socks. Ive tried compression socks, ive tried those stupid charcoal heaters. The only thing that works anymore is letting them go ice cold and then go inside to warm them up and they seem to be alright. But Im just done with it.

What do you guys use for boot heaters. Whats the best ones, Im not worried so much about price I just need it to work. Rechargeable battery would be killer as well.

My toes will think you tremendously!
