The heat-resistant HRO rubber sole, capable of withstanding temperatures up to 300 °C, features variously 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 of very lightweight, foamed EVA, which effectively absorbs shocks and impacts when the heel strikes the ground. The breathable material of the sole wicks moisture away from the feet and, combined with the water-absorbent and antibacterial coated upper material, 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 conventional steel caps, and is both non-magnetic and heat-insulating. In this ultra-lightweight 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 tremendous flexibility.
