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.

Rubber: The rubber sole is a traditional and highly reliable element in the construction of footwear, valued especially for its extreme mechanical resistance and grip. This contact layer is made of natural or synthetic rubber, which is characterized by its high density and elasticity. Due to its physical properties, it provides excellent traction on a wide range of surfaces, from smooth asphalt to unpaved terrain. In addition, the rubber is naturally waterproof and resistant to temperature fluctuations, ensuring stability and a secure stride in a variety of climatic conditions.
