Textile: The textile upper of the sneakers is lightweight, breathable and comfortable, ideal for everyday wear and sports. It ensures air circulation, keeps feet fresh and adapts to their shape. Often complemented with synthetic or rubber details for durability and support.

Vegan leather: A sustainable and ethical alternative to animal leather, which is becoming increasingly popular in the footwear industry. It is made from synthetic materials (such as polyurethane - PU or recycled polyester) or from innovative natural sources such as pineapple leaves (Piñatex), apple peels, cork or even mushrooms. Modern vegan leather is designed to closely mimic the look and texture of real leather, while often offering greater water and stain resistance. Its main advantage is that there is no animal suffering in its production and it often has a significantly lower ecological footprint, especially when it uses recycled or vegetable-based ingredients.

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 outsole provides excellent grip and durability on a variety of surfaces. Thanks to its elasticity, it absorbs shock, increasing comfort when walking or running.
