  • How HygroHeat™ Works

    • HygroHeat™ is Laetts’ patented thermal technology that generates warmth through embedded ceramic particles.
    • These particles emit far-infrared rays (FIR) to support circulation and thermal retention during activity.
    • The white line is woven with reflective yarns to return body heat inward — no batteries, no external power needed.

  • Up to 8.8℃ Warmer

    • Independent testing confirms that Laetts socks retain up to 8.8°C more warmth than standard Merino.
    • This warmth comes from our patented ceramic yarn core, designed to trap and reflect body heat.
    • The result is longer-lasting comfort in cold conditions — without the bulk of heated liners or battery systems.

    How BootGlide™ Works

    • BootGlide™ is our patented friction-tuned design that makes it easier to slide boots on and off.
    • It optimizes the interaction between sock fabric and boot liner to reduce grabbing and bunching.
    • Designed for the beginning and end of every outing — when comfort, cold fingers, or tired legs matter most.

      Worth the price

      I was skeptical at first and I was told I need to invest in good ski socks. Been wearing basic or wool socks this whole time and WOW.... what a life change. I have sweaty feet and they always get cold and it ruins my skiing a little. These socks regulate heat and trap moisture. A must have for any skier!!!

      Very high quality

      I've had these socks for 2 months now and I've started using them outside of skiing. They're EXTREMELY comfortable and perfect for the cold. I live in -10 degrees C weather and with these socks I don't have to wear thermal leggings. I rave about these socks all the time!

      10/10 recommend! Warm, supportive, breathable, YES!

      My custom liners require a thinner sock, and these provided a perfect middle of the line thin feel that was warm and breathable. The compression was noticeable after riding when my dogs weren’t barking as bad as normal, and my calves and shins were supported the entire day of skiing! Good for any level skier for maximum comfort and feel

      Best boot sock on the market!

      I have been using the Laetts Compact Comfort socks for the past three months in my ski boots and fishing waders. They are fantastic for ease in getting in and out of the boots and waders. Most of all, they are much warmer that other socks that I have used. I would highly recommend them for any outdoor activity.
