The Alaska TRX boot comes with the metal-free nail protection. The PU leather upper, 100% wool lining, heat-reflective Alu insoles and Sievi TractionPro® friction sole guarantee a comfortable user experience in cold weather. These safety boots have water-repellent PrimaLoft® thermal insulation made of 90% recycled materials. Side-zip provides added comfort.

Aluminium

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 aluminium toe cap is 50 % lighter than conventional steel toecaps.

Composite PS

The perforation resistance meets EN ISO 20345:2022 requirements: the perforation resistance is 1100 N. The perforation resistant midsole is tested with a 3 mm conical nail.

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

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.

Double density PU/RU

The footwear sole consists of polyurethane and rubber. The PU/rubber friction sole features excellent grip and wear resistant properties. The mid-layer of the sole is made of shock absorbing FlexStep® material. Heat resistant up to 300°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.

Heat resistance

The footwear is suitable for use in hot conditions. Sievi’s nitrile rubber sole withstands temperatures up to 300 °C.

Zipper & shoe laces

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

Ankle protection

The ankle has PORON XRD® support (Lazer Roller High+) or viscoelastic memory foam that moulds itself to the wearer's foot, supporting the ankle and absorbing shocks.

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.

ESD

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.

PrimaLoft®

The footwear has PrimaLoft® thermal insulation, which is made with 90% recycled materials. Water repellent, breathable and very light, PrimaLoft® thermal insulation keeps your feet dry in all conditions.

FlexStep®

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.

TractionPro

Sievi TractionPro® is a sturdy friction sole that gives stronger grip on slippery surfaces. The unique sticky rubber sole, together with the FlexStep® interlayer, developed by Sievi, ensure that the sole remains flexible in all conditions. The Sievi TractionPro® sole's structure and design, with its deep and sharp-edged tread profile, are designed to maximise friction and maintain grip on different surfaces.
