The Viper product family now includes the ViperX Roller H+ S3, which comes with a new textile nail protection X midsole as well as with a Boa®M4 -roller mechanism. The upper material is breathable and durable split leather. Breathability is enhanced by an effective moisture-wicking 3D-dry® lining. Added support is provided by memory foam ankle protection which, with heat, moulds to the shape of the wearer’s foot.

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.

Composite X

The product’s penetration resistance meets the requirements of standard EN ISO 20345:2011. Prevents sharp objects from penetrating through the sole. Designed to meet the requirements of the new stricter standard EN 22568-4 (2019) which requires the penetration resistant midsole to be tested with a 3 mm nail with a square tip instead of the 4.5 mm nail required by the current standard. (e.g. construction industry).

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/TPU

The double density sole consists of polyurethane and elastic
thermoplastic polyurethane. The outsole is wear resistant and
the mid-layer is 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).

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.

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.

Memory foam ankle protection

The ankle part of the footwear is protected by viscoelastic memory foam which moulds itself to the shape of the wearer’s foot, providing personalised support and softness. Memory foam supports and protects the ankle from shocks.
