AES (AntiStatic-ESD-Solutions bvba) * ESD prevention clearly distinguish the difference between an ESD work shoe and an ESD Safety Shoe. ESD shoes, have an electrostatically dissipative conductive shoe sole, popularly known as antistatic shoes (which is not the same, incorrectly). Safety Work Shoes are classed as ESD safe shoes when the resistance value of the system person-shoe-floor is below 3,5 x 10^7 resp. 35 MOhm according to EN 61340-5-1.
