S7S is a safety class from the updated standard EN ISO 20345:2022: a waterproof shoe with a profiled sole and a metal-free puncture-resistant midsole, tested with a thin 3 mm nail. In practice, this is the successor to the familiar S3 shoe, with waterproofing over the entire shoe instead of just a water-repellent upper material. The range consists of sporty mid-height and high models from Puma, Albatros, Sixton and Redbrick, often with additional features such as a heat-resistant sole (HRO) or cold insulation (CI). Metal-free is convenient if you regularly have to pass through metal detectors.
