      OUR SOLES, OUR FIELD OF EXPERTISE

      A key criterion for the safety and well-being a work shoe or work boot offers to its wearer is the quality of the outsole. Material, tread depth and tread design must be suited for the respective areas of application. Numerous variants are possible and depend on the particularities and specific conditions of a workplace. We help you to find the right sole so that you are perfectly equipped for your work.

      TREAD DESIGN 

      An ergonomic tread rib configuration ensures improved rolling of the feet and prevents fatigue. Rounded tread edges ensure a safe footing on the ground.

      TREAD DEPTH

      Sufficient height of the tread profile and individual tread bars is particularly important on uneven surfaces. Deep treads deliver superb grip. Self-cleaning characteristics are also important to avoid accidents caused by dirt sticking in the treads.

      TYPE OF SOLES - MONO VS DOUBLE DENSITY

      The major benefit of double-layered soles is that two different materials can be used.

      For example, the outsole can be produced from rubber and the midsole from PU. This combines the advantages of both materials: The superb heat resistance of rubber and the comfortable impact absorption properties of PU.

      By contrast, the advantage of a single-layered sole lies in the fact that a single material can be injected with a lower density. This results in a lightweight sole, which adjusts well to different ground and floor conditions.

      MATERIALS 

      RUBBER - robust and heat-resistant

      Rubber outsoles are exceptionally sturdy: short-term temperature-resistant up to 300°C, tough to penetrate by sharp-edged objects and resistant to fuel, oil, microbes and numerous chemicals. Special manufacturing processes make them abrasion-resistant. However, rubber is heavier than PU and TPU, and is somewhat less flexible at cold temperatures.

      POLYURETHANE (PU) - flexible and sturdy

      PU outsoles can withstand temperatures of up to 130˚C and are flexible at temperatures down to -30˚C. Similarly to rubber soles, they are resistant to oil and fuel, numerous chemicals and microbes, and are abrasion-resistant, although they are much lighter. A particular advantage of the material: the good impact absorption characteristics, resulting in improved cushioning and wearing comfort.

      THERMOPLASTIC POLYURETHANE (TPU) - extremely abrasion-resistant

      The characteristics of TPU outsoles are comparable to those of PU. But they are even more efficient as a result of a special manufacturing process. With enhanced abrasion-resistance they are even more durable, and also their non-slip properties are stronger. Another advantage of TPU outsoles is their higher elasticity and resistance to the cold.

      01 BEVELLED PROFILE RIBS Particularly good grip on uneven ground. Increased stability and exceptional non-slip properties made possible by tread ribs, which are bevelled in the stopping or push-off direction. This makes the safety shoe highly versatile in every weather and on any surface.
      02 ERGONOMIC ROLLING An S-line runs through the entire outsole tread and supports the natural rolling action of the foot: Setting the heel down on the outer edge, rolling over the mid-foot in the direction of the ball of the foot – a movement that precisely follows an S-line.
      03 FLEX GROOVES facilitate improved physiological rolling of the foot and easier physiological bending during kneeling activities.
      04 LIMITING THE RISK OF STUMBLING AND TWISTING Both ends of the sole exhibit a negative profile, which prevents „sticking“, in particular with turning movements and when setting the foot down.
      05 SOLE CORE MADE OF INFINERGY® FROM BASF Cushions impacts and bounces back into its original shape extremely well when the pressure is being reduced, thus the energy is transferred back to the wearer. Learn More
      06 HONEYCOMB Increased slip resistance on smooth industrial floors. These ensure good slip resistance and optimum stability when standing.
