Customer Reviews

Hotronic Heated Socks
Socks work great. Thin enough to fit in my plug race boots with lace up liners. You don't feel heat, but your toes just don't get cold. The App is excellent. Very easy to setup and use!

Over the years, I have tried various devices to keep my feet warm during outdoor activities in NH in the winter. I like the socks because I can use them in any of my boots, so I bought a spare pair so I can wash one and wear one. Changing the heat setting on the battery pack isn't easy if you are wearing layers, so I usually set it to Level 2 for most conditions.
