Sievi 52204 Auto S2 safety shoe

The Auto S2 is a classic safety footwear model from Sievi with a lightweight aluminium toecap. The upper material is durable and water-repellent PU coated leather with lace-up fastening. The full length insoles are anatomically shaped providing added comfort. Available in sizes EU 35-47 (UK 2.5-13).
 
The aluminium toecap protects toes from falling objects and compression and is 50 % lighter than traditional steel toecaps. It meets the requirements of the EN ISO 20345:2011 standard: shock resistance is 200 J and resistance to compression 15000 N.
 
The microporous FlexStep® sole material developed by Sievi allows for exceptional shock absorption and flexibility and creates excellent friction on slippery surfaces. The construction of the FlexStep® flexible sole eliminates stress and shocks to the feet and spine helping to prevent foot and back pain. The FlexStep® flexible sole is featured on all Sievi footwear. SRC rated for slip resistance.
 
As with many styles in Sievi's range the Auto S2 is ESD (ElectroStatic Discharge) rated having a low electrical resistance (between 0.1 and 100MΩ). This prevents a build-up of static electrical charges in the human body by sending these charges to the ground in a very safe and controlled manner. They guarantee to prevent the sudden flow of electricity between electrically charged objects caused by contact.
