Sievi Viper 1+ S1
Sievi Viper 1+ S1
Durable and sporty shoes with composite toecaps. Upper material is breathable and water-resistant microfibre, ventilation perforations and 3D-dry® lining in the upper material make these shoes extremely breathable. Double-layer soles are extremely durable and flex grooves ensure that the shoes are highly flexible. FlexStep® soles for excellent shock absorption.
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.
Double density PU/TPU
The double density sole consists of polyurethane and elastic
thermoplastic polyurethane. The outsole is wear resistant and
the mid-layer is of shock absorbing FlexStep® material.
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 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.
Footwear designed with antistatic features, discharges the
body’s static electricity up to tolerances of 100 kΩ - 1000 MΩ.
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
