Lace-up shoes made of durable PU-coated leather with aluminium toecaps and penetration resistant steel midsoles. Polyurethane soles are resistant to oil and a number chemicals and absorb shocks effectively. Breathable and structured insoles and 3D-dry® lining improve ventilation and make the shoes comfortable to wear. ESD-approved.
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. The aluminium toecap is 50 % lighter than traditional steel toecaps.
The steel midsole, prevents sharp objects from penetrating through the sole. Meets the requirements of the EN ISO 20345:2011 standard: resistance to nail penetration is 1100 N.
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 20345:2011 standard.
Antistatic footwear releases in a controlled manner static electricity accumulated in the body. The resistance limits are 100 kΩ - 1000 MΩ.
The upper material used in this footwear is water repellent. Its water resistance meets the requirements of the EN ISO 20345:2011 standard.
Shock-absorption of the heel is a requirement of EN ISO 20345:2011 and EN ISO 20347:2012 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.
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.
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.
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.
