Toecap, 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.
Penetration resistant midsole, composite
The penetration resistance fulfills the same EN ISO 20345:2011 requirements as traditional midsole made of steel. Steel, however, gives greater penetration resistance, which is why Sievi recommends a steel midsole for the more demanding conditions (e.g. construction industry).
Resistance to oil and many chemicals
Sievi’s sole resists oil and many chemicals. The oil resistance of Sievi footwear meets the requirements of the EN ISO 20345:2011 standard.
Antistatic
Footwear designed with antistatic features, discharges the
body’s static electricity up to tolerances of 100 kΩ - 1000 MΩ.
Water repellent
The upper material used in this footwear is water repellent. Its water resistance meets the requirements of the EN ISO 20345:2011 standard.
Shock-absorbing heel
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.
Sole material 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.
DUAL insole
The Sievi DUAL Comfort insole has shock absorbing cushions made of PORON® material which adds comfort to your feet and back.
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).
BOA® Closure System – more user comfort
Easy to use and durable, the patented Boa® Closure System signifi cantly increases the wearer comfort of the footwear.

Dry feet with 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.
FlexStep® – Grip and flexibility to work
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.
