LAETTS™ began with a frustration familiar to anyone who spends long days in boots—cold feet, difficult boot entry, and changing conditions that challenge comfort and performance. What began as a practical problem became a broader pursuit: engineering socks around the realities of the footwear environment.
Today, LAETTS approaches sock performance through Integrated Performance—bringing together material selection, responsive thermal technology, friction management, and purpose-built construction so each element contributes to how the sock performs as conditions and activity change.
You may also see our name styled as Laetts™—the same brand and the same performance philosophy, expressed through a different typographic mark.
From Prototype to Patent
From early field testing to U.S. patent approval, LAETTS evolved through years of material research, prototype development, athlete feedback, and system-level engineering.
Year One
Serious development begins with a focus on FIR integrated thermal yarns.
BootGlide™ emerges
Field testing leads to the BootGlide™ concept—a mapped approach to reducing friction where sock and boot interact most.
HygroHeat™ finalized
HygroHeat™ is finalized as LAETTS' responsive thermal technology, while core sock constructions continue to evolve through extended field testing.
From Innovation to Market
U.S. patent protection, growing retail expansion into New England and the Mid-Atlantic, and a KSL 5 television feature mark LAETTS' transition from product development toward broader market recognition.
Our Founders’ Story
One founder—Dr. Mark Blaisdell, a lifelong skier—grew tired of wrestling with tight boots at the beginning and end of every run. That recurring problem led to BootGlide™, a patented mapped-zone construction designed to reduce friction at key sock-to-boot interfaces and make boot entry and removal easier.
The other founder—Jinglu Huang, a trade journalist with a deep focus on material innovation—had been following advances in functional yarns and far-infrared ceramic technologies. That research contributed to the development of HygroHeat™, LAETTS' moisture-responsive thermal technology engineered to support warmth as conditions change.
Supporting these technologies is the Merino Thermal Foundation—LAETTS' material platform for combining Merino's natural moisture and comfort properties with engineered fibers, yarns, and purpose-specific sock construction.
These elements came together through Integrated Performance: an engineering approach in which materials, technologies, fit, and construction are designed to perform as coordinated parts rather than isolated features.
That approach ultimately led to LAETTS' U.S. Patent No. 12,501,946, protecting an integrated sock architecture built around the realities of performance inside footwear.
From two different starting points—boot interaction and material science—LAETTS developed a common philosophy: engineer the sock as a complete performance environment.
Featured on KSL 5 — The Noon Show
LAETTS joined KSL 5's The Noon Show to share the story behind the brand, demonstrate its performance socks, and discuss the real-world problems that inspired a different approach to performance inside footwear.
Our Commitment
We're here for people who keep moving—even when conditions don't.
Whether skiing, hiking, hunting, fishing, working outdoors, or simply spending long days in boots, changing temperature, moisture, activity, and footwear demands can continually reshape comfort.
LAETTS designs around those changes. Through Merino-based material foundations, responsive technologies, and purpose-built construction, we engineer socks to work with the footwear environment rather than treating warmth, fit, and comfort as separate problems.
The goal is simple: help people stay comfortable, move more naturally, and spend more time outside.
