OnSteam®: soft, breathable microfibre lining

Leather: A traditional natural material obtained by processing animal skins, valued in the shoe and haberdashery industry for its inimitable combination of durability, breathability and aesthetics. Thanks to its unique fibrous structure, the leather is able to adapt perfectly to the anatomy of the human body, ensuring high user comfort. It is a "living" material that breathes naturally, absorbs moisture and acquires a characteristic patina over time. Depending on the processing method (smooth leather, suede, nubuck), it offers different degrees of resistance to external influences and different surface textures.

Rubber: It is one of the most widely used materials for the production of soles due to its high mechanical resistance and durability. The main advantage of rubber soles is their excellent grip (traction) on different types of surfaces, which minimises the risk of slipping. The material is naturally flexible, waterproof and effectively absorbs shocks during walking. Depending on the compound, the rubber can be either soft for better contact with the ground or hard for maximum abrasion resistance on rough terrain.

TrueSense® GS1: Premium barefoot sole designed for perfect surface contact while maintaining maximum durability. This blend of special synthetic rubber excels in its extreme flexibility in all directions and high abrasion resistance. With a thickness of just 4 mm (including the tread), it provides an authentic "barefoot" experience, stimulating nerve endings in the feet and supporting natural walking biomechanics. Despite its low profile, it offers reliable foot protection and ensures stability even on wet urban surfaces thanks to its non-slip pattern.
