Bounce midsole: In contrast to conventional PU midsoles, the PU material of the Bounce midsole contains a significantly higher number of small air bubbles. These ensure optimum cushioning for the entire foot and at the same time save a significant amount of weight. Duo PU sole: Abrasion-resistant, robust and yet flexible - this sole runs and runs and runs. The tread pattern ensures high slip resistance, even on wet surfaces. The translucent sole material is ideal for working on sensitive floors. 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 sole area ensure good ventilation. Electrostatic charges are dissipated away from the body. FAP penetration protection: A flexible penetration protection made of ceramic-coated fibres protects the entire surface of the foot from penetrating objects and still supports the flexibility of the shoe. Steel toe cap: Steel toe cap with large toe clearance for greater comfort. Upper material: The upper material is made of robust, extremely durable full-grain cowhide that is resistant to wear and tear. The smooth, soft material offers optimum protection against moisture penetration and is easy to clean.
