Cobra Roller High+ S3
Cobra Roller High+ S3
An ankle boot with a composite toe cap, steel midsole protection and memory foam to support the ankle. Excellent grip and wear resistance is guaranteed by the Sievi TractionPro® friction sole which has a sporty profile to provide great grip and shock absorption, especially in areas where the foot needs support. The FlexEnergy® heel component absorbs kinetic energy and returns more than 55% of that energy to the wearer.

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.
