Product Information

The Best Electric Socks in the World just got better with Toe Cap Surrounding Heat and a natural material mix of merino wool and silk.

Set Lithium Pack rcB 1200 + Heat Sock 5.0 Toe Cap

These aren't your Grandpa's electric socks! We at CozyWinters have wanted to sell Battery Heated Socks for over 12 years now, but could never find a product worthy to sell to our customers. There are many cheapy rechargeable heated socks on the market, that use D-cell batteries, but none can come close to the quality or performance of these Austrian designed and European Alps tested rechargeable heated socks. All the other socks that we have ever tested, did not heat evenly and you could feel the wires and heating elements, plus the battery packs were bulky, clumsy and could not perform in cold temperatures.

These slim fitting (rechargeable) Lithium power packs, snap in at the top cuff of the socks and have push button settings and built-in Bluetooth Smart, so you can easily regulate the heat to your preference, with 3 different heat settings from the power button on the batteries, or infinite settings from our app on your Smartphone. Unlike most batteries, these proprietary Lithium power packs were designed to perform in extreme cold temperatures, and can heat up to 14 hours on the low setting. Plus, these Bluetooth-heated socks have the same Impulse Control technology that was developed for high-end ski boot heaters, which stimulates blood circulation while in use. These Heated Socks have been very popular in Europe and now you can experience the comfort.

Our top quality Battery Powered Heated Socks are one of the most versatile foot warming solutions available. These electric sock warmers fit both Men's and Women's feet. 

New Lenz Heat App:
No more need for a remote, you can adjust the amount of heat in your socks with you Smart Phone. Use the new Lenz heat app to quickly and easily regulate the heat control of the battery. It also provides you with an overview of the current charging status of your battery. If you don't have a Smart phone you can still control the temperature from the power button on the batteries.
