The Nike InfinityRN 4 is a high-cushion shoe designed for daily training and long-distance easy runs. It features the new ReactX midsole, delivering higher energy return and a softer feel than the previous React. The thick midsole, rocker geometry, and wide forefoot platform enhance stability and stride smoothness. The Flyknit upper is soft,贴合, and breathable, with a well-designed collar and tongue for overall comfort. The full rubber outsole offers good durability, though grip on wet surfaces is slightly lacking. Overall the shoe feels soft and stable, ideal for midfoot or heel strikers doing daily mileage and recovery runs. Testers note stable performance in the 5:30–6:30/km pace range, making it a great choice for runners seeking comfort and support. If you are looking for a daily trainer with high cushioning, stable support, and eco-friendly理念, the InfinityRN 4 is one of Nike's most trustworthy options.
