In the forefoot and midfoot regions, a perforated EVA structure enhances ventilation and allows the insole to flex smoothly during propulsion. The midfoot area includes a black EVA reinforcement section with an integrated blue cushioning pad, providing mild support and additional comfort without restricting natural foot mechanics.

The contoured side profile offers slight guidance for foot alignment and stability, making the insole suitable for a broad range of sport and active footwear. The combination of EVA and GEL elements ensures durability while maintaining a lightweight feel that does not compromise shoe fit.
