Antistatic

Antistatic footwear releases in a controlled manner static electricity accumulated in the body. The resistance limits are 100 kΩ - 1000 MΩ.

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.

Metal free

No metal parts are used in the footwear and metal detectors do not react to them.

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.

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.
