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.

Synthetics: The material of the upper includes a wide range of man-made fibres and laminates that are designed to overcome the limits of natural materials. The main advantages are low weight, high strength and fast drying ability. Modern synthetic materials are often developed with an emphasis on breathability and resistance to external influences such as moisture or mechanical damage. Thanks to their technological variability, they allow the production of specific textures and structures that provide the foot with the necessary support and flexibility while maintaining easy maintenance.

GEL™: Silicone gel technology in the midsole, developed in 1986. The gel inserts - located in both the heel and forefoot - effectively absorb shock, dissipate vibrations and ensure a smooth stride transition. The combination of GEL™ with foam layers promotes comfort, stability and natural movement.

AHAR+: (Asics High Abrasion Rubber Plus) is an advanced version of the high-resistance rubber that the ASICS brand uses on exposed parts of the sole. It is a carbon-infused compound that is strategically placed in the areas of greatest stress (especially on the heel). Compared to standard rubber, AHAR+ is 50% more abrasion resistant, which significantly extends the life of the shoe even for hard impact runners. Despite its extreme stiffness and durability, this compound is designed to be lighter than previous generations and provide excellent traction on road and paved trails.
