Sandal from the Sievi AirRacer range with Velcro fastening and aluminium toe cap. The FlexEnergy component, the world’s most advanced shock-absorbing heel, stores kinetic energy and gives a greater than 55% energy return. The SieviAir® sole dissipates the perspiration created by the heat of the feet through special ducts. The PU sole provides good grip and is resistant to many chemicals.

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.

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.

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.

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®

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.

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.

Antistatic

Antistatic footwear releases in a controlled manner static electricity accumulated in the body. The resistance limits are 100 kΩ - 1000 MΩ.

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.

FlexEnergy

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.

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.

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.
