We developed Hiemx for riders who generate power on cold days. The durable shaft features a Gore-Tex® PFC-free membrane that guarantees waterproofing and breathability so moisture doesn't build up during activity. Inner Gore-Tex soft fleece keeps the cold out and acts as a thermal regulator. The sole is designed for the highest grip levels and prevents constriction that restricts circulation, thereby maintaining body temperature. Our unique high-density rotary closure system is designed to withstand riding impacts and the Dyneema® cable securely holds the shoe throughout the ride. Firmor lateral support guarantees greater foot stability on technically challenging rides.
