Sievi Racer Free Roller S1P size 45

Racer shoes feature the world’s most advanced heel cushioning, built around the Sievi FlexEnergy flexible element. The element absorbs the kinetic energy generated while walking, and more than 55% of that energy is returned to your step. The sporty lightweight construction, breathable and anatomically supportive design, and the comfort-enhancing Boa® fastening system make Racer Free a superior safety shoe.
