What are the best heated Lenz socks to buy?



Information Guide

Just wanted to let you know that the socks arrived today and were, of course, the right model and size. My daughter is ecstatic as she has fairly severe Raynaud's phenomenon but refuses to give up skiing. You guys are top shelf!”

-Best Wishes, Ken

Finally! Say goodbye to frozen feet and hello to warm toes all day long. Lenz is an Austrian manufacturer that specializes in heated gloves, socks, and vests.

Not just for the alpine adventurers, these warming wonders can help all sorts of chilly folk.

For people with Raynaud’s Syndrome, the cold can set in even without heading outside, and getting warm again can be very difficult. Restricted blood vessels make Raynaud Disease sufferers susceptible to the cold with any change of temperature.)

The Lenz Heated Sock is a functional sock with an integrated heating element you don’t notice. By using the Lenz Heat App and Bluetooth, you are able to quickly and easily regulate the 3 heat control settings of the sock battery. Providing heat for up to 14 hours in the toe and sole region, the Lenz Heated Socks are designed with optimal moisture transportation, additional shin padding, and ring bandages for optimal support on the foot and only require a short charging time. The Lithium Packs are easily attached by means of a press stud on the leg band.


Lenz heated socks are made from Merino wool. Merino wool is an ideal material for outdoor clothing. The unique properties of merino wool clothing make the material comfortable to wear with excellent heating properties, natural breathability, highly elastic, light, and fast drying with its natural wicking ability, pulling moisture away from your skin.

Because Merino can still scratch and chafe when you wear it for long periods of time, the socks include an inside layer made from yarn that ensures the socks provide high durability and non-scratch comfort.

Popular activities for the Lenz sock include:

  • Skiing
  • Snowboarding
  • Snow Adventure Touring
  • Hunting & Fishing
  • Photographers
  • Biking & Golfing
  • Riding
  • Running
  • Travelling

  • Work - Markets
  • Freezer & Cool Room industry workers


This advanced battery design has been created to control the batteries remotely with a Bluetooth controller. Innovation plus and so user-friendly! Please note that these socks cannot be shipped by Express Post unless your delivery address is near Melbourne due to the Lithium batteries and aviation rules. Please allow sufficient time for regular post shipping times by Australia Post.

The 1200 battery stays warm for approximately 4 hours on high, 6 or 7 hours on medium and 10 to 14 hours on low.
The 1800 battery stays warm for approximately 6 hours on high, 9 to 11 hours on medium, and 16 to 20 hours on low.
The 1200 batteries are slightly smaller in size and thickness compared to the 1800 batteries. The 1200 batteries can last up to 14 hours while the 1800 can last up to 20 hours.

Lenz Battery Pack Guide


Lenz Mobile App

This mobile app is compatible with both Apple and Android devices, allowing you to control the batteries through your mobile phone. The pro version of the app allows you to control two additional batteries (giving a total of four). This means you can control your socks and a vest or gloves at the same time. It also allows for a slider option for heat control, rather than the 3 settings.

You can intelligently control the heating using the Lenz heat app and it provides an overview of the current state of charge of all lithium packs.
INTERVAL FUNCTION - Heating and pause times can be set individually with the interval function, which extends the lithium packs’ lifetime.

Finding the right size LENZ Sock for you.

Like any ski socks, Lenz socks should be worn firm and close to your skin with minimal wrinkles to ensure a smooth surface within your boots. This will minimise any wrinkles cutting off circulation or causing discomfort.

As a general rule, a good place to start would be:

  • 35-38 - will fit women who say they have a small foot (size 7 and under)
  • 39-41 - will fit most women (size 8 - 10), and men who say they have a small foot (size 6-8)
  • 42-44 - will fit most men (size 9-11) and women who say they have a big foot (size 10.5 +)
  • 45-47 - will fit men who say they have a big foot (size 12 +)

Of course, if there are any problems, we can assist with returning and exchanging for another size as per our normal return policy :) 

Purchase a spare pair of the Lenz Heated Socks to ensure you have optimal warmth this winter over multiple days. A spare pair means less frequent washing, which is what everyone wants! Everyone knows the cleaner the sock the warmer they are.
