Leather: Natural leather is a traditional material resulting from the tanning process of animal hides and skins, which occupies a key position in the footwear and haberdashery industry due to its mechanical resistance, breathability and aesthetic value. The specific reticular structure of the collagen fibres allows the material to adapt to the user's anatomy, resulting in optimum wearing comfort. As a hygroscopic material, the leather naturally regulates moisture and ensures air circulation. The appearance and functional properties, such as the degree of water repellency or texture, are defined by the specific type of technological processing, which include smooth finishes, suede or nubuck.

Cork-latex: A traditional natural compound used in midsoles for its exceptional anatomical shaping ability. This combination of crushed cork and natural latex creates a firm but flexible support that adapts to the wearer's foot individually over time. The material excels in excellent insulation, breathability and natural shock absorption. It is a sustainable and highly comfortable choice that promotes a healthy posture and ensures comfort even during all-day wear.

Regular

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.
