The heat-resistant HRO rubber sole, capable of withstanding temperatures up to 300 °C, features differently shaped profile elements that ensure optimal mobility and secure ground contact. The reinforcement of the pivot point significantly reduces friction and, consequently, fatigue. The ldCell element in the heel area is made from very lightweight, foamed EVA, which effectively absorbs shocks and impacts when the heel is engaged. The breathable material of the sole wicks moisture away from the feet, and in combination with the water-absorbent and antibacterial coated upper material, it creates a perfect base climate. The anatomically shaped footbed complements the high performance standards of the urban series. A newly developed fiberglass composite toe cap offers more freedom, is lighter than traditional steel caps, and is non-magnetic and heat-insulating. In this ultra-light midsole, countless small air bubbles provide optimal cushioning and enhance the rolling motion of the foot. The highly flexible fabric conforms snugly and lightly to the human foot, fitting like a sock without pressure points. The knitted shaft made from Safety, a blend of high-quality synthetic fibers, offers remarkable durability despite its extraordinary flexibility.
