PrimaLoft® insulation and teddy lining together with the aluminium and wool insoles ensure excellent heat insulation. Thanks to the metal-free, penetration-resistant textile insole and the metal-free composite toecap, the shoes are light to wear while still keeping the feet safe. The flexible PU soles provide excellent grip, making the shoes comfortable and safe to wear even in winter conditions.

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.

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).

Primaloft®

The footwear features thermally insulating and breathable Primaloft fi bre. Primaloft fi bres improve the thermal
insulation by binding more air molecules between the body and the outside air.

Warm lining

Footwear displaying this symbol can be worn in cold
environments. The material keeping the cold out is either lamb’s
wool or artifi cial fur. Additionally, some styles are lined with
Thinsulate™ fi ber.

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.

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 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.

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).

Thermo Alu

DUAL insole
The Sievi DUAL Comfort insole has shock absorbing cushions
made of PORON® material which adds comfort to your feet
and back.

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.

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.

Metal free

Footwear displaying with this symbol is metal free. The footwear is light, and metal detectors do not react to it. It fulfils the requirements of the EN ISO 20345:2011 standard.
