BENEFIT: BOOST, WARM, WATERPROOF, WICKING, RESPONSIBLE DOWN STANDARD
WEIGHT: 20 OUNCES
Upper: Primaloft® 200g insulation material for more warmth, even in wet conditions. Upper: CLIMAPROOF® membrane for waterproof protection in wet conditions. Midsole: Boost™ offers endless energy in the mountains and high adaptability on rocky surfaces.
Climaproof® acts as a barrier to the elements while allowing heat and perspiration to escape through evaporation.
BOOST is a groundbreaking innovation in cushioning. It provides more energy return than any other foam cushioning material in the running industry, combining soft comfort with responsive energy for the ultimate running experience. In the heat, in the cold and after countless kilometers, it performs more consistently and doesn't lose its cushioning properties like standard EVA.
PrimaLoft® sport is lightweight, breathable and offers superior water repellency, so you remain dry, warm and comfortable even under the most extreme conditions. It uses a microfiber structure to help the body retain warmth and conserve energy. The PrimaLoft® insulation core creates millions of air spaces suspended in the microfiber mesh. These air spaces are so fine that water drops bead on the surface. Even when forced into the PrimaLoft® core, water is repelled and not absorbed by the microfiber structure, so PrimaLoft® keeps you warm even under wet conditions.
STEALTH rubber creates extremely high friction due to its fine balance of viscosity and elasticity, meaning it flows into microporous cavities on all surfaces. This enhances your grip as the rubber is penetrating more of the surface thus creating a better bond.
