I spend a lot of time hunting in tree stands in the bitter Midwest winters. These socks are a lifesaver! They will last as long as you want them to. The great part about the 5v option is having the ability to use bigger battery supplies. I can easily run mine all day keeping my toes and feet warm! Worth every penny!

Sometimes after wearing, I find that the button seems to have gotten pushed by pants or somehow and the heat setting has changed. Button should be harder to push or to lock in the setting. Higher capacity battery would be better for longer lasting.

I ski a lot here and these socks keep my feet nice and toasty.

Love them so much. Kept my feet warm.

Was unsure at first because none of the heated socks I used before sustained me but these heat my feet for EIGHT hours. Comfy too!
