The SieviAir Roller combines two top features: The BOA® Fit System and SieviAir® system. BOA® guarantees an excellent fit, while the pumping mechanism guarantees that the shoes are comfortable to wear throughout the working day. The open design of the upper guarantees maximum ventilation and comfort.

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.

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.

FlexStep®

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 fl exiblity providing excellent shock
absorption.

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.

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.

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

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.

SieviBalance®

SieviBalance® torsional stiffener improves the rotational rigidity of the footwear and control of the foot, which reduces strain to the ankles.

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.

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.
