Safety sandal Sievi 52385 Air R4 Roller

The side-placed lacing mechanism BOA® Fit System increases the comfort of use of the shoes. The world's most advanced heel cushioning FlexEnergy binds the upright kinetic energy and over 55% of the energy returns to the stage. The SieviAir® sole design removes from the shoe the moisture that arises from the feet getting warm, through flow channels in the sides of the bottom of the sole.
