ESD footwear are shoes with an electrically conductive substructure in order to avoid static charge and damage to electronic components by static discharge.
According to the test method as per ÖVE/ÖNORM EN 61340-4-3, the electric volume resistance of such shoes must be within the range of 10 to the power of 5 Ohm (100 kilohm) and 10 to the power of 8 Ohm (100 megaohm).
There are three classes, which have to be marked with "conductive class 1, 2 or 3" in the shoe. ESD shoes are intended for EPA working areas and marked with the ESD icon.
ESD: Electrostatic discharge
EPA: Electrostatic protected area
