Product description
THERM-IC Performance S.E.T. + 1400B heated sock is a complete set with thin merino socks, two Bluetooth batteries, and a charging cable.
Complete heating system for tight ski boots: The set combines a slim S.E.T. sock with the S-Pack 1400B. This provides active warmth around the toes without adding as much bulk as older heated socks.
How to use the product
- Choose the size so the sock fits smoothly and the boot does not become tighter.
- Charge both batteries before use.
- Attach the batteries to the socks and select the heat level on the battery or in the app.
- Start on a low setting for even warmth over a longer period.
- Remove the batteries before washing and let the socks air dry.
