The new, ultra-light AER55 models from the dual.IMPULSE line are remarkably sporty thanks to their innovative upper. The trendy color combinations and the AER55 lettering on the inside of the shoe form further modern design elements. The breathable BREEZE with sandwich mesh material completes the innovations of the well-known safety shoe line. As usual, the new models also come with double-foamed IMPULSE.FOAM midsole with an energy return of up to 55% for fatigue-free working and ultimate comfort.
