Breathable and sporty shoe with Boa® Fit System 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.

Microfiber

The upper material of the footwear is microfibre, which is fast drying and very resistant to frequent washing.

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® sole solution takes care of your feet and improves footwear comfort. The SieviAir® system dissipates the perspiration from the shoe through special ducts in the side of the sole. Under the perforated insole there is a filter, which is connected to exhalation channels. With every step you take the filter is compressed, resuming its original shape when the foot is lifted. This movement produces a pumping action, improving the ventilation of the shoe. SieviAir® really allows your feet to breathe!

FlexStep®

The shock-absorbing heel area protects the feet and the skeletal system against stress. The product meets the requirements of EN ISO 20345:2011 and EN ISO 20347:2012: the shock absorption capacity of the footwear is at least 20 J. The cushioning effect is guaranteed by the use of FlexStep® sole material in all Sievi footwear.

FlexStep®

The microporous FlexStep® sole material, developed by Sievi has been re-designed. The re-designed sole material maintains its excellent shock absorbing properties and flexibility in freezing conditions more efficient. The footwear sole therefore remains softer, even in heavy freezing conditions, and maintains excellent friction on slippery surfaces. The construction of the FlexStep® flexible sole eliminates stress and shocks to the feet and spine, helping to prevent foot and back pains and thereby improving work efficiency. The FlexStep® flexible sole is featured on all Sievi footwear.

Antistatic

Footwear designed with antistatic features, discharges the
body’s static electricity up to tolerances of 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 tolerances for the resistance of Sievi footwear are stricter
(100 kΩ-35 MΩ) than for ordinary antistatic footwear
(IEC 61340-5-1).

FlexEnergy

The Sievi FlexEnergy is a flexible component integrated in the entire heel part of the shoe. With this component the shoe provides maximum shock absorption and excellent wearer comfort for long working days, regardless of the working environment. The component is made of BASF’s TPU Infinergy®, which is the first expanded thermoplastic polyurethane in the world.

BOA® Fit System

Delivering fit solutions purpose-built for performance, the Boa® Fit System is featured in products across industries (in medical, sports and workwear) and 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 effortless precision delivering a connected, fast, customized and durable fit, and is backed by The Boa Guarantee.

Sievi Dual Comfort

The Sievi DUAL Comfort insole has shock absorbing cushions made of PORON® material which adds comfort to your feet and back.

Resistance to oil and many chemicals

Sievi’s sole resists oil and many chemicals. The oil resistance of Sievi footwear meets the requirements of the EN ISO 20345:2011 standard.
