Birkenstock Madrid Eva

Synthetics: The material of the upper includes a wide range of man-made fibres and laminates that are designed to overcome the limits of natural materials. The main advantages are low weight, high strength and fast drying ability. Modern synthetic materials are often developed with an emphasis on breathability and resistance to external influences such as moisture or mechanical damage. Thanks to their technological variability, they allow the production of specific textures and structures that provide the foot with the necessary support and flexibility while maintaining easy maintenance.

EVA: 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.

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.
