Easy to put on and classic safety shoe with lightweight aluminium toecaps. Upper material is durable and water-repellent PU coated leather. Flexible FlexStep® sole absorbs impacts to back and legs, reducing muscle fatigue.

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.

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.

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.

Sievi Green Comfort

Recycled materials account for 67% of the total weight of the materials used in the insole. The surface material is polyamide, which is incredibly wear resistant and wicks moisture from the feet to the lower layer of the insole. The insole is antibacterial and odourless. The heel design keeps the foot’s fat pad in an optimal position, and the insole conforms to the shape of the foot and rebounds to its original shape when the footwear is taken off. Antistatic and machine washable at 40°C.

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.

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.
