Northwave Extreme XC GTX Shoes Black. Winter shoes made of Duratherm Gore-Tex® thermal membrane, which protects against the wind and rain, ideal for adverse weather conditions with temperatures down to -10ºC. They stand out for the Carbon XC 12 sole with an index of 12, carbon and TPU inserts in strategic areas for greater traction and the S.L.W.2 micrometric closure, which together with the Xframe construction, the Artic 4Layer insole and the Easyfit Climaflex neoprene ankle with Gore-Tex membrane, make it a comfortable and practical shoe for cycling on cold and rainy days.

Main features:

• Patented Xframe® construction made of ultra-light state-of-the-art materials with a thickness of only 0.5mm that allows a perfect transfer of each watt of power with maximum fit and comfort without pressure points.
• With Duratherm Gore-Tex® membrane that is waterproof and windproof, which provides perfect moisture absorption and keeps feet perfectly insulated and warm even in the coldest weather conditions.
• Incorporating highly abrasion resistant rubber reinforcements that guarantee 360º protection on the entire back.
• Easyfit Climaflex ankle area, which combines the extreme elasticity of the Gore-Tex Rattler® membrane with the high thermal conductivity of neoprene, ensuring unprecedented mobility and protection.
