The closed and padded tongue prevents the ingress of dirt and the formation of pressure points. The collar padding ensures good stability and support in the shoe. In direct contact with the upper material in the area of the protective toe cap, the abrasion-resistant toe protects the upper material in this critical area against premature wear. Hydrophobic nubuck leather is resistant to wear and tear. Furthermore, the textile material Cordura was used, which is also very tear and abrasion resistant. It is also dirt and water repellent. A Gore-Tex climate membrane prevents water from penetrating the shoe, but is still breathable. Ergonomically shaped steel toecaps protect the Innox Work GTX blue Mid S3 from impact and pressure. The full-length, replaceable insole is antistatic.
