That "something extra" is electrostatic dissipative technology that prevents static discharge, in addition to standard Reebok sneaker support. These are warehouse-worthy safety footwear, but they've got game when it comes to style and comfort.
RESIST THE SURGE.
Static discharge is a dangerous beast. It can ignite flammables, interfere with manufacturing, and damage sensitive electronics. The Reebok Dual Resistor Static Dissipative technology protects you and your workplace with protection that exceeds ASTM standards for electrostatic dissipation. The resistors provide a precise range of 1-10 MegOhms, and there are two of them, so you always have a fail-safe back-up.
