Runner Roller TR+ S3L
Runner Roller TR+ S3L
The metal-free structure of the Runner Roller consists of a composite toe cap that provides good insulation against heat and cold as well as flexible textile nail protection. The Sievi TractionPro® friction sole guarantees excellent grip and wear resistance. Sievi TractionPro® has a modern design and a flared base for added comfort and shock absorption, especially in areas that support the foot.

Composite
The toecap protects toes from falling objects and compression. Meets the requirements of the EN ISO 20345:2022 standard: shock resistance is 200 J and resistance to compression 15 000 N. The composite material toecap is completely metal free and insulates well against heat and cold.

Composite PL
The perforation resistance meets EN ISO 20345:2022 requirements: the perforation resistance is 1100 N. The perforation resistant midsole is tested with a 4.5 mm conical nail. Steel, however, gives greater perforation resistance, which is why Sievi recommends a midsole made of steel or the PS composite textile for more demanding conditions (e.g. the construction industry).

Shock-absorbing heel
Shock-absorption of the heel is a requirement of EN ISO 20345:2022 and EN ISO 20347:2022 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.

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.

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.
