The PUMA Fast-R Nitro Elite 2 features an ultra-breathable mesh upper, which provides excellent ventilation, keeping the feet cool and dry during long races or intense training sessions. This design choice enhances comfort and reduces the likelihood of overheating, which is crucial for maintaining optimal performance.

Equipped with PUMA's NITRO Elite foam, the midsole of the Fast-R Nitro Elite 2 offers a blend of lightweight comfort and superior responsiveness.

The Fast-R Nitro Elite 2 generally fits true to size with a design that accommodates a narrow toe box, making it suitable for runners with slimmer feet. The shoe's sock-like upper secures the foot, providing a snug, supportive fit that enhances overall stability.

This model is designed with comfort in mind, featuring a decoupled heel that adapts to different foot strikes. The combination of the NITRO Elite foam and the breathable upper ensures a comfortable experience, even during extended periods of wear.
