Work Well
November 7, 2023
They heat the toes well but the battery at high may last around 3 hours. I had to use high heat to feel that they worked well in 20 deg weather. Unfortunately they do not heat the heels of your feet so my heels did get cold. They work via bluetooth from your phone. You have to turn them on at the battery which is located at the top of the sock. You can turn them off with your phone but you cannot turn them back on with your phone. This is a flaw in my opinion - bluetooth is nice but not the opportunity to turn on with your phone.

It's very important that you make sure the battery is well place into the sock. I had a battery come out while walking but got it in time.
  • Heats well
  • Turn off with bluetooth and adjust heat
  • Turn on at the battery.
  • Battery needs to last longer at high heat.
  • Devise velcro at battery compartment to insure battery doesn't come out
  • Can't turn on with cell phone - bluetooth
  • No heat at heel of foot.

Awesome socks.
February 1, 2023
I tried these socks under my waders fishing winter steelhead late January. I set them at 25% power so it would last 8 hours. I’m in the cold water in my waders and has no problem all day long. Usually my toes would be ice cycles. I have never been so comfortable. We was on the water in and out of the boat all day. I immediately noticed when the batteries ran out. They lasted 8 hrs I was out there for 9 1/2. The last hour my feet was freezing. I’m so thankful I got these socks! Usually cold feet is my struggle out there in the winter. Not anymore!

  • It would be cool if they would last longer at 50% I
