Why should you choose S3 if the safety class S5 already covers all eventualities? Well, S3 shoes are more attractive than their S5 counterparts, because they are offered in a variety of finishes like leather, textile, microfibre and more – and they are available in various colours. What’s more: they are extra comfortable. A plastic or rubber exterior is required for S5 to guarantee 100% waterproofing. S3s, however, only have to offer membrane-aided waterproofing up to 60 minutes, which means they are more breathable.
If you require a waterproof safety boot, you can choose from plastic or rubber boots as well as models of protection classes S6 and S7. In both protection classes, a permanent protection against water penetration is part of the standard requirement - unlike S3 shoes. Nevertheless, many Strauss S3 safety boots are permanently waterproof due to the implemented membrane, making them comparable in characteristics to S7 safety shoes.
