How does a shoe manufacturer make the “Meg Ohm” shoe and make it a Meg Ohm each time?
That was the question haunting the shoe companies for decades. Shoes are made up of many layers, compounds, materials, etc. Each of which have their own variability which usually makes the total resistance of a shoe unable to be controlled tightly. Many manufacturers will state that their ESD shoes are “below 100 MegOhms.” That is because the nature of the shoe manufacturing process tends to only allow an upper limit not a controllable range. Ironage has developed their Chip -Tec ESD Shoe using a flexible circuit to connect the inside of the shoe to the bottom of the shoe. Just like the resistor of a wrist strap makes the value of that connection very repeatable at 1 Meg Ohm., the new Chip-Tec circuit allows the Ironage ESD shoes to have a resistance to ground according to ESD STM 97.1 of a “Meg Ohm.” That makes them quite different in the world of shoes. Ironage has brought the art of manufacturing ESD into the 21st Century with the “Meg Ohm” shoe. The shoes come in a varity of styles
