Warm boots with a composite toecap and a penetration-resistant textile midsole. The PU-reinforced toecap improves wear resistance. Zip fastening on the side and lacing on the top. PU leather upper retains its shape and is water-repellent. Reflector on the side of the boot. Fur lining and ALU insole for warmth. FlexStep® sole is flexible and offers excellent grip even in freezing temperatures.


The toecap protects toes from falling objects and compression. Meets the requirements of the EN ISO 20345:2022 standard: shock resistance is 200 J and resistance to compression 15 000 N. The composite material toecap is completely metal free and insulates well against heat and cold.

Composite PL

The perforation resistance meets EN ISO 20345:2022 requirements: the perforation resistance is 1100 N. The perforation resistant midsole is tested with a 4.5 mm conical nail. Steel, however, gives greater perforation resistance, which is why Sievi recommends a midsole made of steel or the PS composite textile for more demanding conditions (e.g. the construction industry).

Resistance to oil and many chemicals

The footwear sole resists oil and many chemicals. The oil resistance of Sievi footwear meets the requirements of the EN ISO 20345:2022 standard.


Antistatic footwear releases in a controlled manner static electricity accumulated in the body. The resistance limits are 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 20345:2022 standard.

Shock-absorbing heel

Shock-absorption of the heel is a requirement of EN ISO 20345:2022 and EN ISO 20347:2022 standards: the shock absorption of the footwear must be at least 20 J. In all Sievi footwear the cushioning effect is guaranteed by the use of FlexStep® sole material, see FlexStep® for more information.

Single Density PU

The footwear sole is made of FlexStep® material. This single density microporous structured polyurethane sole offers very high slip-resistance and flexibility providing excellent shock absorption. Heat resistant up to 120°C.

Warm lining

The footwear is suitable for cold conditions. Depending on the model, the insulating material is lamb’s wool, artificial fur or PrimaLoft® insulation.

Zipper & shoe laces

The shoe features a zip and lace fastening, making them easy to put on and take off.

ALU insole

Sievi ALU insole features a heat-insulating aluminium layer. The aluminium foil of the insole reflects the cold out and the heat inward.


Through its sole construction, ESD footwear provides a safe and controlled method of discharging the body’s static electricity. The resistance limits 100 kΩ - 35 MΩ for the Sievi ESD footwear are stricter than for antistatic footwear (IEC 61340-5-1). Wearing ESD footwear can help you avoid damage to sensitive electronic equipment.


The microporous FlexStep® sole material developed by Sievi maintains its excellent shock absorption and flexibility in freezing conditions. The structure of the FlexStep®flexible sole prevents strain on the feet and spine and absorbs shocks. The FlexStep® flexible sole is featured on all Sievi footwear.
