The heat socks 6.1 toe cap merino compression are the first heat socks with Toe Cap heating element, compression knitting technology and high merino wool content. The improved fit at the cuff offers more comfort when worn and no uncomfortable cutting.

The very thin design makes the heat socks 6.1 toe cap merino compression perfect for race boots. The ring bandage and special protectors on the toe and heel ensure an optimal fit.

The fit of the socks is anatomically optimized and very close. Thanks to the compression knit technology, signs of fatigue occur later during physical exertion. This ensures more energy and performance.

The high percentage of merino wool in combination with functional fibers provides a pleasantly warm and dry feeling and transports sweat away in a targeted manner.

Compatible are all types of Lenz lithium packs, which can be attached to the waistband of the socks by means of the snaps.

The Lenz Body heat system warms the body from head to toe. The lithium pack rcB 1800 can be used for all models of the Lenz heated socks, heated vest, heated bandage, heated gloves, heated pants and the LED system.

The lithium packs are connected with push buttons. The lithium packs are small, light and provide up to 20 hours of heat at the touch of a button for work, sports and leisure.

This increases the ability to perform and concentrate, even in cold temperatures, and ensures that blood circulation is maintained.

The lithium packs rcB 1800 can be controlled directly on the lithium pack. With the Lenz heat app, however, the heat can also be regulated continuously via smartphone. Optimal when the lithium packs are under several layers of clothing.

Worth the cost !
March 1, 2024
I recently visit Mount Tremblant Canada for a skiing trip and was very concerned about the cold weather . I have always experienced debilitating cold hands and feet while skiing . Over the past 7 years a day of skiing has turned into 2 hrs of skiing because my feet are so numb and cold.
These socks are a great value for me because I was able to ski Sunday thru Thursday without any cold or numb feet! My batteries stayed charged after a full day of skiing. I kept the battery rather high on a 6 or 7 and adjusted the level to low as we too lunch breaks . One afternoon around 3:30p my batteries needed to be charged and within minutes , I felt the cold boots and my toes became uncomfortably cold . It's pretty amazing how they keep your toes so toasty warm. I thought the 1800 battery was a good choice too.
These socks are a game changer and I think this is money well spent to enjoy the outdoors . We have one life to live and for me I love winter and outdoor activities, so I'd like to enjoy my time outdoors and feel cozy while doing it .

6.1 is better than 5.1 - right?
April 13, 2023
The socks work great for sitting still for hours in the cold. My mistake was buying the compression 6.1 instead of the normal fit 5.1. I didn't pick up on and realize how "compressing" Lenz compression is. Initially I tried to put the socks on when I got to the field after hours on the road. That was like trying to give a bobcat an enema in a phone booth. Eventually just accepted the additional wear & tear and that Lenz would have to go on at home. The compression socks are like trying to get your feet in and out of a sausage casing. Once the shock of spending another $170.00 to correct my mistake settles in over the summer, I'll likely purchase the model socks I need.
  • They work.
  • Price. Be sure you buy the ones you need.
