Breathable and sporty half-shoe with Boa® fastening mechanism and aluminum toe cap. The world's most advanced FlexEnergy heel cushioning absorbs the generated kinetic energy and over 55% of the energy is returned to the stride. The SieviAir® sole solution removes moisture generated by the warming of the feet from the shoe through the flow channels on the side of the sole. The PU sole is durable and resistant to several chemicals.
