Designed and manufactured exclusively in Japan, the Zerofit Heatrub Ultimate Socks are now available in two options – Standard Length and Knee Length.
Both sock options have been engineered using the same Heat Threads that exist in the award-winning Zerofit Heatrub Ultimate baselayer which has been independently tested and proven to be five times warmer than a standard baselayer. These Heat Threads on the inside of the garment generate warmth instantly and offer an incredibly cosy and snug feeling of heating happiness!
Following extensive feedback from existing customers, the new Knee Length Heatrub Ultimate Socks have been created to be easier to slip into motorcycling, hiking and skiing boots, as well as golf shoes. To achieve this, the Nano Pods that exist on the sole of the Standard Length Heatrub Ultimate Socks have been removed, while the length of the new socks has also been increased significantly to offer more warmth for the lower half of the leg.

Great news—the Zerofit Heatrub Ultimate Socks ($29) are back in stock and ready to keep your feet warm all winter long. Available in both Standard Length and Knee Length options, these best-selling socks are designed to deliver outstanding warmth and all-day comfort in cold conditions.
Whether you're heading out for an early morning walk, spending the day on the golf course, tackling a winter hike, or enjoying a weekend ride, these socks provide the warmth and comfort your feet need without sacrificing performance.
If you're preparing for the colder months, now is the perfect time to stock up. Choose from Standard Length or Knee Length and experience why the Zerofit Heatrub Ultimate Socks continue to be one of our most popular cold-weather essentials.

To guarantee attention to detail, both styles of the Ultimate Socks are made exclusively in micro factories in Japan, with the Standard Length option featuring Nano Pods on the sole for super grip.
The Knee Length Heatrub Ultimate Socks - 8cm longer than the original standard socks - were created to be easier to slip into motorcycling, skiing and traditional boots, and they’ve also been a game-changer for anglers looking for additional warmth by the bank, lakeside or even in the water under waders.
