The Heckel MACTRACK 3.0 GTX is ideal for those who work in demanding or extreme conditions, such as wet weather, low temperatures, and uneven terrain. Thanks to the GORE-TEX membrane, which provides a waterproof and breathable layer, it keeps your feet dry from the elements and ensures a comfortable internal climate. The rubber outsole provides excellent traction, and the combination of high-quality materials and metal-free protective elements results in safety footwear that is lighter in weight but offers greater flexibility. Upper: leather. Color: black. Size: 36-48.
