Winter Boots Grisport Nubuck Leather WinTherm (-30°C)

Winter Boots Grisport Nubuck Leather with WinTherm Insulation (-30°C)

Winter boots Grisport are crafted for demanding conditions where warmth, grip, and protection are essential. Made from genuine nubuck leather with dual-layer waterproof membranes, these men’s boots feature the WinTherm insulation system and Vibram outsole for dependable performance in cold and wet environments. Designed for temperatures down to -30°C, they combine the advantages of outdoor footwear, trekking boots, and waterproof gear in one versatile model.

WinTherm technology is a high-density thermal membrane that maintains body temperature by reflecting heat inward while blocking external cold. Its aluminum microfibers preserve warmth generated by the feet, while the breathable structure allows moisture to escape. The membrane also incorporates silver-ion treatment for antibacterial and antistatic effects, ensuring long-lasting comfort and hygiene. This balance of insulation and breathability makes WinTherm ideal for extreme winter use without overheating during active movement.
