EN ISO 20345 Certified Safety Footwear
EN ISO 20345 Certified Safety Footwear
ESD stands for electrostatic dissipative. This footwear is built to drain the static charge that builds up on your body steadily to ground, rather than letting it discharge in a sudden spark. That controlled path protects sensitive electronics from damage and reduces ignition risk in flammable atmospheres, which is why ESD is specified in electronics manufacturing, automotive assembly, cleanrooms, pharmaceuticals and petrochemical sites. Every style here is certified to EN ISO 20345 for foot protection, and each ESD-marked model is additionally tested to the tighter resistance band that the ESD standard requires. We hold {inStock} ESD styles across boots, trainers and shoes ready to order.
Your body picks up static charge as you move. ESD footwear gives that charge a controlled, resistive path to ground so it dissipates gradually instead of jumping as a spark. That protects static-sensitive components on the line and lowers the risk of an igniting discharge near solvents, dusts or gases. Every ESD style here is certified to EN ISO 20345. We hold 253 ready to order.
The base antistatic property (marked A) under EN ISO 20345 allows a broad resistance band, roughly 100 kilohms to 1000 megohms, which is enough to bleed off a shock but too loose for sensitive electronics. ESD footwear is tested to a tighter, lower upper limit, typically kept below 35 megohms, so the drain is faster and predictable. If your risk assessment names ESD specifically, an A-rated antistatic boot does not meet it.
Specify ESD where a controlled static path matters: electronics and semiconductor assembly, automotive and battery lines, server rooms and data centres, cleanrooms, pharmaceutical and medical device manufacture, and ATEX zones handling flammable liquids, gases or fine dust. If you work around printed circuit boards or explosive atmospheres, ESD is usually the minimum, not an upgrade.
Most ESD styles here use a composite toecap and non-metallic build, which keeps them light and metal-detector friendly for controlled environments. The range runs from low-profile trainers and slip-on occupational shoes for indoor assembly work to S3 ESD boots for sites that also need a water-resistant upper and penetration-resistant midsole. Match the S-rating to the hazards, then confirm ESD is on the model.

ESD, electrostatic dissipative, describes how footwear handles the static charge that accumulates on a moving body. An ESD shoe keeps the wearer-to-ground resistance inside a controlled window that is low enough to drain charge steadily yet high enough to protect against electric shock, so static leaves the body without the sudden spark that can destroy a microchip or ignite a vapour. The property is verified to the ESD footwear test method and is separate from the A antistatic mark under EN ISO 20345, which covers a much wider resistance band. When a specification or customer audit calls for ESD, look for the ESD mark on the model itself, not just an antistatic rating.
Once ESD is confirmed, the remaining choices are toecap material, the S-rating and fit. Composite toecaps suit most controlled environments because they are lighter, warmer underfoot and pass through metal detectors, and many ESD styles overlap with our metal-free safety footwear range. For indoor assembly a trainer or occupational shoe is often enough, and you can browse the wider safety trainers collection for lace and slip-on options; for sites that also involve wet or sharp-object hazards, choose an S3 ESD build. Our size and fit guide explains how fit varies between brands so you order the right size first time, and eligible individuals buying for work may qualify for VAT relief, which we apply automatically where it applies.
