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.

DUAL Comfort insole

The insole consists of three layers: a soft surface material, a breathable interlayer and a lightweight, shock-absorbing EVA bottom layer. On the heel and under the ball of the foot there
is a PORON® shock absorbing cushion, which absorbs external shocks and reduces strain.

GORE-TEX

GORE-TEX lining is a unique waterproof lining material that allows the feet to breathe while keeping the moisture out of the footwear. This is the only membrane structure on the market systematically tested for its functionality and comfort.

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.
