An ankle boot with a composite toe cap, steel midsole protection and memory foam to support the ankle. It comes with the BOA® Fit System lacing mechanism to make it quicker to put on and take off. The FlexEnergy® heel component absorbs kinetic energy and returns more than 55% of that energy to the wearer. Wide XL fit.

Composite

The toecap protects toes from falling objects and compression. Meets the requirements of the EN ISO 20345:2022 standard: shock resistance is 200 J and resistance to compression 15 000 N. The composite material toecap is completely metal free and insulates well against heat and cold.

Steel

The steel midsole prevents sharp objects from penetrating the sole. Meets the requirements of the EN ISO 20345:2022 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 20345:2022 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.

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 fi ttings see
“XL” in the product name.

Ankle protection

The ankle has PORON XRD® support (Lazer Roller High+) or viscoelastic memory foam that moulds itself to the wearer's foot, supporting the ankle and absorbing shocks.

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.

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.

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.
