The Science Behind Laetts: A Layered System of Performance Technologies
At Laetts, warmth starts with science. Our patented HygroHeat™ technology forms the foundation of nearly every sock we make — a powerful Far Infrared (FIR) thermal system engineered directly into the yarn. But we don’t stop at heat.
Building on HygroHeat™, we created the Laetts Merino Thermal Sock System — a next-generation material blend that merges nature’s best fiber with performance-driven insulation. The result is a new class of socks that outperform traditional Merino and conventional thermal gear in every condition.
From there, we layer in other smart innovations:
- BootGlide™ our patented friction-reducing system, makes boots easier to get on and off.
- Compression supports circulation, reduces fatigue, and enhances recovery — especially when combined with warmth.
Each technology is thoughtfully engineered, often working in tandem. Whether you're carving down slopes, fly fishing in icy streams, or riding through cold wind, Laetts socks are designed to keep you warm, supported, and ready for whatever lies ahead.
HygroHeat™
keeps your feet warm by reflecting and amplifying your natural body heat. The ceramic particles ensure a dry, warm, and odor-free experience, whether you're facing freezing temperatures on the slopes or hiking in the cold.
Laetts Merino Thermal System™
The Laetts Merino Thermal System is more than just a sock material — it’s a new way to stay warm outdoors. By pairing extra-fine Merino wool with our patented HygroHeat™ technology, we’ve created a lightweight system that delivers lasting warmth, moisture control, and all-day comfort. Designed for active use in cold
conditions, it sets a new standard in performance insulation.
BootGlide™
With BootGlide™, slipping into your boots becomes effortless. The friction-reducing fibers ensure your feet are comfortably in place, reducing the strain and preventing discomfort during wear.
Laetts Compression
Laetts redefines compression with an integrated system that combines graduated pressure and HygroHeat™. This dual-function design boosts circulation, stabilizes muscles, and delivers active warmth—unlocking performance benefits no standard compression sock can match.
