Lazer Roller High+ S3
Lazer Roller High+ S3
The Lazer Roller High+ ankle boot includes our FlexEnergy® element, which is visible through the cut-out in the heel of the shoe. This allows it to move more freely, thus increasing the flexibility of the shoe. The Sievi TractionPro® friction sole ensures excellent grip. The ankle features PORON XRD® support, which moulds itself to the wearer’s foot to support the ankle and absorb shocks.

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.

FlexEnergy
The flexible FlexEnergy® component is integrated in the entire heel part of the shoe and provides maximum shock absorption of kinetic energy, with more than 55 % of the energy returned to you. The component is made of BASF’s TPU Infinergy® material, the world’s first expanded thermoplastic polyurethane.
