ESD safety low shoe Flash 5255 XP BOA S3S SR, BOA Fit System, width 10 - Atlas 70600

Anyone passing through a cleanroom airlock twenty times a day loses time on laces. The Flash 5255 XP BOA closes with a dial, one handed, with gloves on and evenly across the whole instep. Underneath sits a full safety shoe in class S3S SR to EN ISO 20345:2022, with an aluminium toe cap rated for 200 joules, a metal-free XP penetration-resistant insert and an ESD resistance below 100 MOhm to DIN EN 61340-5-1.

What the shoe does on the shop floor

• ESD shoe to DIN EN 61340-5-1. In the person-shoe-floor system the resistance stays below 100 MOhm, so the wearer's charge drains off in a controlled way instead of discharging into a component.
• BOA Fit System with a dial closure. The shoe closes to the millimetre with one hand, gloves on, and opens again in seconds.
• Aluminium toe cap (alu-tec), tested to EN ISO 20345 for 200 joules of impact energy and 15 kN of compression. Aluminium weighs less than steel and forms no cold bridge across the forefoot.
• Metal-free XP penetration-resistant insert made from aramid fabric. It covers the full sole area, weighs less than a steel midsole and leaves the foot its natural torsion.
• SportLine upper, an air-permeable textile fabric that keeps the shoe light and moves perspiration outwards.
• MPU REBOUND SYSTEM in the sole. It absorbs impact energy at the heel and returns it into the roll-off, which is what counts across eight hours of standing and walking.

Technical data

Areas of use

Cleanroom and cleanroom preparation, electronics manufacturing and assembly lines, maintenance and warehousing in EPA zones, wherever shoes come off and go back on often.

Standards and conformity

Class S3S to EN ISO 20345:2022 means, in plain words: closed heel area, antistatic build, energy absorption in the heel, water-repellent upper, cleated outsole and penetration resistance. The trailing S marks the metal-free penetration-resistant insert, tested with the 3.0 mm nail. SR stands for slip resistance on ceramic with glycerine. For the ESD workplace, DIN EN 61340-5-1 is the governing standard. It measures the person-shoe-floor system, and the value has to stay below 100 MOhm. At the lower end the shoe standard caps the resistance at 0.1 MOhm so that the shoe still insulates during work up to 230 V. The antistatic range of the shoe standard itself runs from 0.1 MOhm to 1,000 MOhm.

The shoe is personal protective equipment of category II under PPE Regulation (EU) 2016/425. The model is approved for orthopaedic insoles to DGUV rule 112-191, the marking inside the shoe is what counts. The EU declaration of conformity is provided by the manufacturer ATLAS-Schuhfabrik in Dortmund.
