The men's Puma ForeverRun NITRO blends cushioning and stability for a smooth-as-silk ride. A newly developed NITRO midsole uses a soft core with a firmer rim to give you both comfort and stability, while an asymmetrical heel counter keeps your feet centered and aligned throughout your stride. A wider medial rubber segment guides the foot and stabilizes any excess overpronation during the later stages of your gait. The engineered mesh upper is airy and breathable and uses PWRTAPE targeted reinforcement for support and durability mile after mile. Plus, the PUMAGRIP performance rubber outsole gives you confident traction on all surfaces from the road to the track. Lightweight and stable, the Puma ForeverRun NITRO delivers smooth cushioning for your runs, walks and everything in between.
