The Sixton Ortisei is a robust and waterproof safety boot S3. The upper material is made of soft split leather and a soft yet durable microfiber. The lasting waterproofness is ensured by the OutDry membrane, which also provides high breathability. The 3D inner lining is breathable and allows air to circulate well through a channel system. The strong grip and abrasion-resistant Vibram outsole is suitable for all temperatures and offers the highest slip resistance class SRC. The toe cap in the shoe tip area ensures a longer lifespan for the shoes. The DynaFit insole is ergonomically designed and anatomically shaped, providing perfect cushioning with an EVA core. The metal-free K+ Antiperforation Plus penetration protection offers maximum flexibility.
