Composite
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.
Steel
The steel midsole, prevents sharp objects from penetrating through the sole. Meets the requirements of the EN ISO 20345:2011 standard: resistance to nail penetration is 1100 N.
Microfiber
The upper material of the footwear is microfibre, which is fast drying and very resistant to frequent washing.
3D-dry
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
absorption.
SieviAir®
Developed and patented by Sievi, the SieviAir® system dissipates the moisture generated as the feet warm up through exhalation channels 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, returning to its original shape when the foot is lifted. This movement produces a pumping action, improving the ventilation of the shoe.
FlexStep®
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.
FlexStep®
The microporous FlexStep® sole material developed by Sievi maintains its excellent shock absorption and flexibility in freezing conditions and creates excellent friction on slippery surfaces. The construction of the FlexStep® flexible sole eliminates stress and shocks to the feet and spine. The FlexStep® flexible sole is featured on all Sievi footwear.
Antistatic
Footwear designed with antistatic features, discharges the
body’s static electricity up to tolerances of 100 kΩ - 1000 MΩ.
ESD
Through its sole construction, ESD footwear provides a safe and
controlled method of discharging the body’s static electricity.
The tolerances for the resistance of Sievi footwear are stricter
(100 kΩ-35 MΩ) than for ordinary antistatic footwear
(IEC 61340-5-1).
