AL Hit Weld XL+ S3HRO
AL Hit Weld XL+ S3HRO
AL Hit Weld is a good choice particularly for welding work: the heat-resistant sole withstands temperatures up to 300°C and the stitching is in heat-resistant Kevlar. The FlexEnergy® heel component, the world’s most advanced shock-absorbing heel, gives 55% energy return. The product meets the requirements of standard EN ISO 20349-2:2017, footwear protecting users against the heat risks and molten metal splashes occurring in welding work.

Aluminium
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.

Steel
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
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.

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.

Heat resistance
The footwear is suitable for use in hot conditions. Sievi’s nitrile rubber sole withstands temperatures up to 300 °C.

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.

FlexEnergy
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.

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.

3D-dry
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.

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.

Footwear for welding work
The flame symbol indicates that the footwear meets the requirements of the welding standard EN ISO 20349-2:2017 and protects against heat and splashes of molten metal.
