The HRO rubber sole, which is heat-resistant up to 300°C, is based on the latest running shoe technology. The sole profile ensures optimum mobility and secure contact with the ground. The gel cushion embedded directly in the heel area acts like a trampoline - it absorbs shocks and energy and then returns it immediately in the form of bounce. This anatomically shaped, lightweight footbed with a waffle structure keeps you cool and dry by wicking moisture away from the foot during wear. The shoes also dry extremely quickly after taking them off. The highly flexible textile fabric moulds snugly and easily to the human foot. Thanks to its unrivalled fit, it sits like a sock without any pressure points on the foot. The upper made from a blend of high-quality synthetic fibres offers enormous durability despite its enormous flexibility. In this ultra-lightweight midsole, countless tiny air bubbles ensure optimum cushioning and improve the rolling motion of the foot. The TPU torsion control in the centre of the sole supports foot movement and ensures greater stability.
