PU sole. Abrasion-resistant, robust and yet flexible - this sole runs and runs and runs. The tread ensures high slip resistance, even on wet surfaces. The translucent sole material is ideal for working on sensitive floors. Advanced Cell. Non-slip inlay for excellent cushioning and grip on dry and wet floors, enables optimum joint protection and maximises foot stability. Evercushion Pro ESD. The soft PU material of this insole offers optimum cushioning from the moment you step on it to the end of the movement, thus relieving pressure zones. Fine perforations in the front of the sole ensure good ventilation. Electrostatic charges are dissipated away from the body. Steel toe cap. Steel toe cap with large toe clearance for more comfort. Bounce midsole. The PU material of the Bounce midsole contains a significantly higher number of small air bubbles than in conventional PU midsoles, which provide optimum cushioning for the entire foot and at the same time significantly reduce weight. Oiled nubuck leather has a similar velvety character to nubuck leather, but is more supple and offers even more protection against moisture penetration. It also prevents premature ageing, even with little care.
