Storm XL+ S3
Storm XL+ S3
PrimaLoft® insulation and warm lining together with the aluminium and wool insoles ensure excellent heat insulation. Thanks to the metal-free, penetration-resistant textile insole and the metal-free composite toecap, the shoes are light to wear while still keeping the feet safe. The flexible PU soles provide excellent grip, making the shoes comfortable and safe to wear even in winter conditions.
Composite
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. Toecap made of composite material is completely metal free and insulates well against heat and cold.
Composite
The penetration resistance fulfills the same EN ISO 20345:2011 requirements as traditional midsole made of steel. Steel, however, provides better protection against the thinnest nails, which is why Sievi recommends a steel midsole or SieviSole-X® composite textile midsole for the most demanding conditions (e.g. construction industry).
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
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 20345:2011 standard.
Shock-absorbing heel
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.
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.
XL-last
Sievi XL ranges. These extra wide styles offer more space and
comfort for the wearer. For footwear with XL width fi ttings see
“XL” in the product name.
Thermo Alu
Sievi ALU insole features a heat-insulating aluminium layer. The aluminium foil of the insole reflects the cold out and the heat inward.
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.
Primaloft®
The footwear is equipped with Primaloft® thermal insulation made with 90 per cent recycled materials. Waterproof, breathable and extremely light, Primaloft® thermal insulation keeps your feet dry in any 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.
