Safety boots
Shoes
ESD safety boots and ankle-high safety shoes (MID) close the upper above the ankle and support the ankle joint, whereas a low shoe ends below it. The dissipative sole ties the wearer into the personnel grounding system: the shoe itself measures between 10⁵ and 10⁹ Ω to EN ISO 20345 and therefore counts as antistatic, while the ESD verification comes only from the system resistance person-shoe-floor of less than 3,5 x 10⁷ Ω to DIN EN 61340-5-1. Class S3 versions with a water repellent upper, penetration resistant midsole and cleated outsole are the common design, alongside lined models with CI cold insulation. The category holds 22 models in 241 sizes from Atlas and PUMA Safety in sizes 34 to 53 and widths 8 as well as 10 to 14.
| Design | Upper | Typical equipment | Use |
|---|---|---|---|
| Low shoe (for comparison) | ends below the ankle | S1 to S3, light mesh and leather uppers | Production, laboratory, indoor work |
| Ankle-high shoe (MID) | just above the ankle | S3 and S3S, penetration resistant midsole | Assembly, maintenance, logistics |
| Safety boot | high shaft | S3 with water repellent smooth leather, cleated sole | Outdoor work, construction site, yard |
| Thermal boot | high shaft, lined | S3 CI, fleece lining | Chilled areas, winter duty, outdoor storage |
Typical applications: plant assembly and maintenance with ESD requirements on uneven ground; chilled and deep-freeze areas as well as outdoor winter duty calling for CI cold insulation; yard, loading and outdoor storage at electronics manufacturers; site work by service and commissioning staff; test fields and heavy-duty areas with penetration and impact hazards; workplaces with a raised risk of twisting where a supported ankle is required.
