Kompozīts Purngals pasargā pirkstus no krītošiem priekšmetiem un saspiešanas. Atbilst standarta EN ISO 20345:2022 prasībām: triecienizturība ir 200 J un izturība pret saspiešanu 15 000 N. Kompozītmateriāla purngals ir pilnībā bez metāla un labi izolē pret karstumu un aukstumu. Izturība pret eļļu un daudzām ķīmiskām vielām Apavu zole ir izturīga pret eļļu un daudzām ķīmiskām vielām. Sievi apavu eļļas izturība atbilst standarta EN ISO 20345:2022 prasībām. Antistatisks Antistatiskie apavi kontrolēti atbrīvo ķermenī uzkrāto statisko elektrību. Pretestības robežas ir 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. XL-last Sievi XL ranges. These extra wide styles offer more space and comfort for the wearer. For footwear with XL width fittings see “XL” in the product name. 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. 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. BOA® Fit System The BOA® Fit System delivers micro-adjustable precision fit, engineered to perform in the toughest conditions. BOA® Fit System consists of three integral parts: a micro-adjustable dial, a super-strong lightweight lace and low friction lace guides. SieviBalance® SieviBalance® torsional stiffener improves the rotational rigidity of the footwear and control of the foot, which reduces strain to the ankles. 3D-dry® The 3D-dry® lining, developed by Sievi, transfers moisture away from the foot to the second layer of the lining material and further through the upper and away from the footwear. SieviAir® Developed and patented by Sievi, the SieviAir® system dissipates the moisture generated as the feet warm up through exhalation channels in the side of the sole. The insole is perforated and has a filter underneath, which is connected to the flow channels. With every step you take the filter is compressed, returning to its original shape when the foot is lifted. This movement produces a pumping action, improving the ventilation of the shoe. 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.
