Birkenstock Madrid Big Buckle EVA

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.

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.
