Puma Fast-Trac NITRO 4 Wns

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.

NITROFOAM: Puma's midsole, where nitrogen is injected into the foam during production (supercritical foaming). Microbubbles are created, making it lighter, softer and more flexible than conventional EVA/TPU, with better cushioning and energy return.

Pumagrip: High-performance rubber outsole developed by PUMA that provides excellent traction on a variety of surfaces. Ideal for sports activities, it excels in durability and grip in dry and wet conditions.
