Details
The Switchback socks end the cold-toes problem. Heat sits under the toes, where feet get coldest first, and a small rechargeable battery rides on the outer calf, above your boot.
Closes the CoreLoop™
A heated vest or jacket warms the blood at your core. Switchback socks add heat where the loop ends, at your toes and forefoot, the first place feet go numb on a long sit.

- Adjustable heat on each sock. Press the button on the battery to change the heat level.
- Batteries in the box. Two rechargeable batteries and a charging cable are included.
- Made for standing still. Tree stands, ice fishing, bleachers and winter walks.

The science behind CoreLoop™
Brajkovic and Ducharme (2002) found that warming the torso kept fingers warm and nimble better than heating the hands directly, in 3-hour tests at −25°C (−13°F).
CoreLoop™ heat mapping is built on that idea. When you get cold, your body protects your core first and cuts blood flow to your hands and feet. Heat over the core lets warm blood keep reaching them. Switchback socks add heat where the loop ends, under and over the toes.
The 2 heat zones listed for the Switchback socks (toes; forefoot) come from the factory heat-zone diagram for this exact product, so what we describe matches what you receive.
The study tested heated clothing in a lab, not this product. How warm you stay depends on your layers, how active you are and the weather. Related paper: Brajkovic, Ducharme and Frim (2001). How CoreLoop works.

CoreLoop™ heat mapping
Toes are the last stop on the loop, so they cool first on a long sit. Switchback socks add heat under and over the toes, where feet go numb first.
- Toes
- Forefoot
Built on research by Brajkovic and Ducharme (2002), which found torso heating kept fingers warm and nimble better than heating the hands directly. Pair any 2 pieces to save 15%, all 3 to save 25%. How CoreLoop works
Close the loop
Add a second piece and save 15%. Add a third and the whole order saves 25%.
