SIEVIAIR R1 S1 Str. 40

The sole of the SieviAir® sandal conducts moisture and heat away from the foot, provides more than 30% better breathability through the ventilation channels on the side of the sole. Sievi's FlexEnergy® absorbs the created movement energy and gives over 55% return energy. FlexEnergy is the same ultra-light and shock-absorbing sole material used in running shoes.
