Built on the Laetts Merino Thermal System™, this midweight, half-cushion snow sock blends a fine-gauge Merino knit with HygroHeat™ for moisture-responsive warmth without bulk. Designed for ski and snowboard boots, targeted half cushioning at the heel, toe, and shin helps absorb impact, dampen vibration, and relieve boot pressure—while preserving natural flex and precise board feel.

BootGlide™ low-friction zones reduce resistance at key contact points, making boot entry and removal smooth and low-effort. The eco-conscious Merino blend wicks moisture and resists odor, supporting long, cold days on snow across changing activity levels.

Functions

  • HygroHeat™ Thermal Core

    Patented ceramic system reflects body heat using far-infrared (FIR) technology for self-sustaining warmth — without batteries or bulk.

  • BootGlide™ Easy Fit

    Patented friction-tuned design reduces resistance during boot entry and removal — ideal for cold fingers and tired legs.

  • Up to 8.8°C Warmer

    Lab-tested to retain significantly more warmth than standard Merino socks — for longer comfort in the cold.

  • Eco-Friendly Merino Blend

    Made with sustainably sourced Merino wool and performance yarns — soft on skin, lighter on the planet.

  • Moisture-Regulating

    Engineered fibers actively manage sweat and moisture to keep feet dry and comfortable—even under sustained pressure.

  • Natural Odor Control

    Merino’s natural antimicrobial properties help reduce odor — for fresher feet on long days.

  • Adaptive Fit Support

    Comfortable for skiers with reduced strength, post-surgery needs, or limited dexterity — boot entry takes less effort.

    Advanced Technology for Unmatched Warmth & Comfort

    How HygroHeat™ Works

    •  Patented Thermal System
      HygroHeat™ is Laetts’ patented thermal technology that generates warmth through ceramic particles embedded directly into the sock structure.

    • FIR-Emitting Ceramics & Reflective Design
      These particles emit far-infrared rays (FIR) to support circulation and thermal
      retention during activity. The visible white line on the sock is woven with
      reflective yarns that return body heat inward—no batteries, no external power.

    • Performance Warmth, Up to 8.8°C Warmer
      Lab-tested to retain heat better than leading ski sock brands, Laetts’
      HygroHeat™ keeps feet up to 8.8°C warmer.

    • Lightweight Comfort Without Bulk
      All the warmth—without heavy layers. Designed to maintain comfort across changing activity levels while preserving fit precision and mobility.

    Engineered Comfort from First Step In to Final Step Out

    How BootGlide™ Works

    • Patented Friction-Tuned Zones
      BootGlide™ is Laetts’ patented low-friction knit system engineered to reduce grabbing and bunching inside snow boots. It’s built to make getting in and out smoother—without tugging or twisting.

    • Slide In, Glide Out
      Key zones at the heel and instep are engineered with glide-enhancing fibers, making it easier to step into boots and remove them at the end of the day.

    • More Comfort, Less Strain
      Whether you're dealing with cold hands, stiff gear, or tired legs, BootGlide™
      helps you move with ease. It's especially supportive for seniors, post-surgery
      recovery, or anyone looking for added accessibility.

    • Designed for the Beginning and End of Every Outing
      From your first step in to your last step out—BootGlide™ takes the struggle out
      of winter boots, so you can focus on the adventure.
