Birkenstock Arizona Essentials EVA Unisex

EVA: EVA as an upper represents an unconventional but highly functional use of ethylene vinyl acetate (a foam commonly used in midsoles) directly on the upper part of the shoe. This material is most commonly found in the upper of leisure shoes, slippers or specific hybrid models. EVA uppers are completely non-absorbent, extremely lightweight and easy to wash. Due to its moldability, it can be made as a single molding, eliminating seams and increasing durability. While it doesn't offer the breathability of mesh, it is often complemented by laser-cut holes for ventilation. It is ideal for wet environments, near water, or for situations where quick maintenance and light weight are priorities.

EVA: (Ethylene vinyl acetate) is the most widely used midsole material, valued for its extreme lightness and excellent cushioning capabilities. This foam structure contains thousands of microscopic air bubbles that effectively absorb shock and protect the musculoskeletal system. It is highly flexible, resistant to stress cracking and easily moldable, allowing manufacturers like adidas or Altra to create specific zones of support. It represents the ideal standard for soft impact and comfort in sports and everyday wear.
