The models are based on sophisticated know-how combined with a high degree of comfort. It is obvious that the heavy duty pattern of this hard-wearing, up to 572°F heat resistant HRO rubber outsole has been designed for optimum safety. The direct attached lightweight PU midsole gives underfoot cushioning, shock absorption and insulation from uneven ground. The contoured ever cushion BA+ footbed follows the shape of the foot and ensures a natural position, pressure relief and musclestimulation.
