Get 20% Off Socks This Black Friday!

Good news for all Zerofit fans — the Heatrub Ultimate Socks are back in stock and now available at 20% off in both Standard and Knee-Length versions!

These socks have become one of our most loved products, trusted by motorcyclists, anglers, gardeners, skiers, sailors, and hikers for their unmatched warmth and comfort. Whether you’re tackling the outdoors, working in cold conditions, or simply staying cozy at home, the Heatrub Ultimate Socks deliver exceptional performance and durability that keep your feet warm no matter where adventure takes you.

The Knee-Length Heatrub Ultimate Socks, designed to be 8cm longer than the original standard version, offer extra coverage and warmth for those who need it most. These extended socks are perfect for slipping comfortably into motorcycling, skiing, and traditional boots, making them an ideal choice for outdoor enthusiasts.

They’ve also become a game-changer for anglers, providing additional insulation and comfort while spending long hours by the bank, lakeside, or even standing in the water under waders. With these socks, you can stay warmer, drier, and more comfortable—no matter how harsh the conditions get.

Both versions of the Heatrub Ultimate Socks are crafted with the same innovative Heat Thread technology used in the award-winning Zerofit Heatrub Ultimate Baselayer—independently tested and proven to be five times warmer than standard baselayers. These specialized Heat Threads generate warmth the moment you put them on, delivering an incredibly cozy, snug feeling that keeps your feet perfectly comfortable in cold conditions.

Listening closely to customer feedback, Zerofit developed the new Knee-Length Heatrub Ultimate Socks for added practicality and comfort. To enhance comfort and flexibility, the Nano Pods found on the soles of the standard version have been removed, while the length has been extended to provide extra warmth and coverage for the lower legs—making them ideal for all your outdoor adventures this season.

Having the right pair of socks can make a world of difference in your comfort and performance, whether you’re running, working, or enjoying your favorite outdoor activity. The Heatrub Ultimate Socks are designed to provide exceptional warmth, protection, and support — keeping your feet comfortable and energized no matter the season.
