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 that moisture does not accumulate 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 limits circulation, thus maintaining body temperature. Our unique high-density twist-lock system is designed to withstand riding impacts and the Dyneema® cable holds the shoe securely throughout the entire ride. Firmor lateral support guarantees greater foot stability on technically challenging rides.
