MGuard RollerH XL+ S3 HRO
MGuard RollerH XL+ S3 HRO
MGuard Roller is designed for demanding conditions. The integrated Metashield metatarsal protection absorbs impacts by up to 90%. The flexible FlexEnergy component absorbs kinetic energy and more than 55% of the energy is returned to the wearer. The TractionPro sole ensures a maximum grip, and the Dual Comfort insole, BOA® Fit System lacing mechanism and XL fit add to the comfort.
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.
Double density PU/RU
The footwear sole consists of polyurethane and rubber. The PU/
rubber friction sole features excellent grip- and wear resistant
properties and being heat resistant up to 300 °C. The mid-layer
of the sole is of shock absorbing FlexStep® material.
Sievi 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.
The footwear is suitable for use in hot conditions. Sievi’s nitrile rubber sole withstands temperatures up to 300 °C.
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.
Memory foam ankle protection
There is viscoelastic memory foam on the ankle part of the footwear that shapes according to the wearer’s foot, supports the ankle and absorbs shocks to it.
Sievi FLEXENERGY® is a flexible component integrated in the entire heel part of the shoe. This provides maximum shock absorption and excellent comfort. The component absorbs kinetic energy, with over 55% of the energy returned to the wearer. The component is made of BASF’s TPU Infinergy®, which is the first expanded thermoplastic polyurethane in the world.
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
Delivering fit solutions purpose-built for performance, the BOA® Fit System consists of three integral parts: a micro-adjustable dial, a super-strong lightweight lace and low friction lace guides. Each unique configuration is engineered for fast, effortless, precision fit.
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.
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 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.
Sievi’s Metashield® metatarsal guard is integrated into the shoe's structure and absorbs impacts on the instep by up to 90 percent. The guard, made of PORON XRD® material, is very flexible and its molecular structure, together with the shoe's breathable upper material, allows air to circulate and remove moisture from the shoe, making it very pleasant to wear. The Metashield® metatarsal guard offers significantly better protection than conventional safety shoes, without compromising comfort.
