Patented Performance, Engineered as a System
At Laetts, performance is built through material science, functional design, and real-world validation. Every technology we develop is engineered with a clear purpose—solving practical problems while enhancing comfort, warmth, and usability in demanding environments.
Our core technologies—HygroHeat™ and BootGlide™—are protected under U.S. Patent No. 12,501,946, reinforcing our commitment to purposeful innovation and long-term performance. Rather than isolated features, these technologies are designed to work together as an integrated system, knitted directly into the structure of every sock for consistent, durable results in real-world use.
U.S. Patent Portfolio
This issued U.S. utility patent protects Laetts’ proprietary sock technologies, including HygroHeat™ and BootGlide™, which together form the functional core of the Laetts system.
- HygroHeat™ — a moisture-responsive thermal technology using hygroscopic fibers integrated with far-infrared (FIR) ceramic particles to generate warmth when conditions demand it.
- BootGlide™ — a low-friction knit construction engineered with multi-filament, moisture-managing yarns to reduce resistance when entering and exiting boots.
Both technologies are knitted directly into the sock structure, ensuring durability, consistency, and long-term performance — not applied as surface treatments or temporary finishes.
Why Patented Technology Matters
In an industry where many products rely on material sourcing or marketing claims alone, Laetts invests in original engineering and functional protection.
Patented technology ensures:
- Consistent performance across seasons and use cases
- Long-term durability without performance degradation
- Authentic innovation that cannot be easily replicated
For athletes, retailers, and partners, this means confidence—on the mountain, on the trail, and at the point of sale.
Built as a System
Laetts® technologies are engineered as a unified system, not as isolated features. Each component is designed to work together—starting from the material foundation and building upward through function.
At the core is a balanced blend of premium Merino wool and functional yarns, providing moisture control, breathability, and durability. Integrated directly into this foundation is HygroHeat™, our patented far-infrared thermal technology, which converts moisture into radiant warmth for consistent, lightweight thermal performance.
BootGlide™ is added as a precision enhancement to this system. Knitted into targeted zones using low-friction, multi-filament yarns, it reduces resistance during boot entry and exit—without disrupting fit or warmth.
Together, these patented technologies form a single performance system designed for warmth, comfort, and effortless use.
