Safety shoes must meet the highest requirements for consistent and stable production quality. This requirement can only be achieved through efficient, automated, safe and controllable production processes. The surface materials of safety shoes usually include wear-resistant leather, non-slip materials such as polyurethane (PU or PUR), rubber (GU) or thermoplastic polyurethane (TPU). Built-in toe-protecting toe caps made of steel, aluminum or composite materials prevent toe injuries. Permeable protection made of steel, composite material or aluminum to prevent nails or other sharp objects from being inserted into the foot. In addition, modern shock absorption makes the wearer more comfortable. Shoe sole production is the most important and decisive production link related to quality and safety, independent of the type and purpose of safety shoes.
