Functions

  • HygroHeat™ Thermal Core

    Patented ceramic technology reflects body heat using far-infrared (FIR) energy to support self-sustaining warmth without batteries or bulk.

  • Moisture-Regulating Merino Comfort

    Merino fibers naturally manage moisture and odor while engineered fibers help maintain comfort during extended activity.

  • BootGlide™ Easy Fit

    Patented low-friction zones reduce resistance during boot entry and removal for a smoother fit experience.

  • Ultralight Thermal Build

    Engineered for maximum warmth-to-weight performance, this lightweight construction maintains a thin, responsive profile for precise fit inside performance boots.

    ADVANCED MOISTURE-RESPONSIVE THERMAL TECHNOLOGY

    How HygroHeat™ Works

    HygroHeat™ uses ceramic-enhanced fibers engineered to generate and retain warmth through moisture-responsive technology. By converting natural body moisture into heat energy and reflecting far-infrared (FIR) radiation, HygroHeat™ helps maintain comfortable warmth without batteries, bulky layers, or external power. The result is lightweight thermal performance designed to keep feet comfortable across changing activity levels and conditions.

    Engineered Comfort from First Step In to Final Step Out

    How BootGlide™ Works

    BootGlide™ uses strategically engineered low-friction zones at key contact points to reduce resistance between sock and boot. This allows easier entry and removal while maintaining a secure, comfortable fit during long days in performance footwear. The result is a smoother boot experience from first step in to final step out.
