Why We Like the Lenz 5.1 Heat Sock

We gear up with the Lenz 5.1 Heat Sock to keep numb toes at bay on the mountain's chilliest days. This sock features a flat heating system integrated into a mix of high-performing materials for up to 14 hours of all-around warmth. The low-profile, rechargeable battery pack snaps right in and out of the sock cuff and can be controlled directly or from the Lenz heat app on our phone to adjust the temperature.

  • Merino wool blend sock material is moisture-wicking
  • Sock is anatomically knitted for a performance fit
  • Sewn-in 360° heating element provides low-bulk warmth

I gave it as a gift but have feedback to share

Socks do work great but you need to purchase the battery packs to use them which are pretty expensive as well.

be aware- this is not a complete package

SO while you look at the reviews and the tech description- there is nothing that indicated the battery pack is Separate and will cost you another couple of hundred bucks. A bit of smoke and mirrors I think.

Game Changer

I've used it several times
Size Bought:
5' 11"

Wore battery assisted boot heaters while skiing and even then my toes were cold. I suffer from poor circulation, and with heat adjustment using my phone, I am able to regulate heat temp while riding on the chairlift. Hard on the wallet, but when it’s cold and windy the sticker shock is forgiven. The size runs just a little big, I wear a size 9W shoe and suggest trying a medium sock on before purchase. Either way, you’ll be happy.
