SieviAir Roller XL S1
SieviAir Roller XL S1
The SieviAir Roller combines two top features: The Boa® closure mechanism and SieviAir® system. The closure mechanism guarantees an excellent fit, while the pumping mechanism guarantees that the shoes are comfortable to wear throughout the working day. The open design of the upper guarantees maximum ventilation and comfort.
The toecap protects toes from falling objects and compression. Meets the requirements of the EN ISO 20345:2011 standard: shock resistance is 200 J and resistance to compression 15000 N. Toecap made of composite material is completely metal free and insulates well against heat and cold.
The upper material of the footwear is microfibre, which is fast drying and very resistant to frequent washing.
3D-dry lining, developed by Sievi, transfers moisture from the foot to the second layer of the lining and further through
the upper and away from the shoe thus keeping your feet drier and more comfortable.
Single Density PU
The footwear sole is made of FlexStep® material. This single
density microporous structured polyurethane sole offers very
high slip-resistance and fl exiblity providing excellent shock
Developed and patented by Sievi, the SieviAir® sole solution takes care of your feet and improves footwear comfort. The SieviAir® system dissipates the perspiration from the shoe through special ducts in the side of the sole. Under the perforated insole there is a filter, which is connected to exhalation channels. With every step you take the filter is compressed, resuming its original shape when the foot is lifted. This movement produces a pumping action, improving the ventilation of the shoe. SieviAir® really allows your feet to breathe!
SieviBalance improves the rotational rigidity of the shoe and the control of the foot, reducing strain to the ankles and
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.
