Technologies
PROFOAM
Lightweight and highly responsive midsole. Made of EVA, it combines cushioning and great responsiveness.
PUMAGRIP
PUMAGRIP rubber for maximum traction and durability during movements.
NITRO
Advanced technology providing superior responsiveness and cushioning without compromising on lightness, offering a less painful run. The process begins with a small embryo containing high-quality raw materials. The embryo is injected with Nitrogen (nitrogen) in a supercritical state to expand and become extremely light. The expanded part is compressed into the final midsole design.
