RUSH, certified according to EN ISO 20345:2022, was created as an alternative to the Sprint model and, while maintaining the same S1 PS FO SR ESD protection class, it is distinguished by an upper made of multilayer technical fabric. The three-dimensionality of the fabric guarantees greater protection against dust and volatile elements, while maintaining breathability and lightness. The external toecap is reinforced, protecting the underlying 200J aluminium toecap. To complete the picture, there is the ever-present anti-puncture insert in ultralight PS certified fabric (anti-puncture ‘strong’ type) and the practical drawstring lacing for a simplified fit.
