Star Roller is the solution for even the most challenging conditions. To prevent ankle injuries, the ankle part of the shoe is lined with viscoelastic Memory foam padding. The laces are adjusted by turning the dial; the lace mechanism in turn laces the shoes evenly, providing support at the ideal point. New and improved FlexStep® soles maintain their flexibility in sub-zero conditions even better than before, improving the traction of the soles. Metal-free toecaps, thick lining and thermal insoles of the Star Rollers will keep your feet warm. Penetration-resistant steel midsoles provide the best protection against sharp objects.Load a printable productimage

density microporous structured polyurethane sole offers very
high slip-resistance and fl exiblity providing excellent shock
The shock-absorbing heel area protects the feet and the skeletal system against stress. The product meets the requirements of EN ISO 20345:2011 and EN ISO 20347:2012: the shock absorption capacity of the footwear is at least 20 J. The cushioning effect is guaranteed by the use of FlexStep® sole material in all Sievi footwear.
The microporous FlexStep® sole material, developed by Sievi has been re-designed. The re-designed sole material maintains its excellent shock absorbing properties and flexibility in freezing conditions more efficient. The footwear sole therefore remains softer, even in heavy freezing conditions, and maintains excellent friction on slippery surfaces. The construction of the FlexStep® flexible sole eliminates stress and shocks to the feet and spine, helping to prevent foot and back pains and thereby improving work efficiency. The FlexStep® flexible sole is featured on all Sievi footwear.
