Sievi Terrain S3

The new classically elegant and street-credible Sievi Terrain is lightweight and abrasion-resistant, and has an anatomic shape that supports the feet. The Sievi FlexEnergy component in the heel stores kinetic energy and gives a greater than 55% energy return. The upper material is water-repellent nubuck leather and the dual-layer ActionPro soles provide added durability. The Tebox® lining is breathable and abrasion-resistant.

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.

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.

Double density PU/PU

The footwear sole is a very durable double density polyurethane
sole, featuring a mid-layer of shock absorbing FlexStep®
material.

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 maintains its excellent shock absorption and flexibility in freezing conditions and creates excellent friction on slippery surfaces. The construction of the FlexStep® flexible sole eliminates stress and shocks to the feet and spine. 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

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

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

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.

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.
