Birkenstock Madrid Big Buckle Natural Leather Patent Women

Leather: Natural leather is a traditional material resulting from the tanning process of animal hides and skins, which occupies a key position in the footwear and haberdashery industry due to its mechanical resistance, breathability and aesthetic value. The specific reticular structure of the collagen fibres allows the material to adapt to the user's anatomy, resulting in optimum wearing comfort. As a hygroscopic material, the leather naturally regulates moisture and ensures air circulation. The appearance and functional properties, such as the degree of water repellency or texture, are defined by the specific type of technological processing, which include smooth finishes, suede or nubuck.

Natural cork: In the midsole, it represents an eco-friendly cutting edge with unique functional properties. This sustainable material excels in its natural ability to absorb shock and insulate heat, ensuring an optimal climate inside the shoe. A key advantage is its shape memory - the cork adapts individually to the anatomy of the foot over time, providing unrivalled personalised support. It is lightweight, breathable and, thanks to its antibacterial properties, keeps the shoes fresh even during the rigours of all-day wear.

EVA: The most widely used cushioning material in the footwear industry worldwide. It is a lightweight, elastic polymer that is inserted in the form of foam into the midsoles of sports and leisure shoes. This foam contains thousands of microscopic air bubbles that act as miniature shock absorbers. The EVA material is especially valued for its ability to effectively absorb shock on impact while providing a soft, comfortable feel with every step. Its versatility has made it the standard from which all modern cushioning systems are derived.
