Textile: Textile uppers are a lightweight and highly breathable upper construction solution that uses woven or knitted structures of natural and synthetic fibres. This type of upper is valued in the footwear industry for its extraordinary ability to adapt to the shape of the foot, minimising the formation of blisters and ensuring high user comfort. Thanks to the porous structure of the material, textile uppers allow for efficient heat and moisture dissipation, which is crucial for maintaining an optimal microclimate even under increased physical stress. In addition, modern textile processing technologies allow reinforcement zones to be integrated directly into the knit, achieving an ideal balance between stability and flexibility.

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.

Rubber: It is one of the most widely used materials for the production of soles due to its high mechanical resistance and durability. The main advantage of rubber soles is their excellent grip (traction) on different types of surfaces, which minimises the risk of slipping. The material is naturally flexible, waterproof and effectively absorbs shocks during walking. Depending on the compound, the rubber can be either soft for better contact with the ground or hard for maximum abrasion resistance on rough terrain.
