Birkenstock Madrid Big Buckle Nubuck Leather

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.

Natural cork: Sustainable material derived from the bark of cork oak. Prized in the shoe industry for its unique cellular structure, which contains millions of air cavities, giving the material exceptional lightness and shock absorption. The cork is naturally elastic, breathable and has a low thermal conductivity, which ensures an optimal microclimate inside the shoe. One of its greatest strengths is its ability to gradually mould itself to the anatomy of the wearer's foot, providing individual support and high comfort for long-term wear.

EVA: Features a lightweight and highly functional shoe bottom solution that combines cushioning capabilities and structural support. Unlike conventional rubber soles, it features a significantly lower weight and a higher degree of flexibility, ensuring smooth and natural foot movement. The material effectively absorbs vibrations generated by contact with hard surfaces, reducing the stress on the joints and spine. EVA soles are often used in leisure and urban footwear due to their soft tread and ability to retain their shape during everyday use.
