Materials 

Upper 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.

• Polymeric foam material valued for its exceptional lightness, flexibility and ability to absorb shock. In footwear construction, it is mainly used in midsoles, where it acts as a key cushioning layer protecting the musculoskeletal system from hard impacts. The material is made up of thousands of microscopic air bubbles that compress under load and then return to their original shape. EVA is also highly resistant to low temperatures, does not absorb water and is biologically inert, making it a safe and versatile material for sports and leisure footwear. 

Sole 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.
