This obsession with 26.2 miles fueled the creation of what may be the most impactful running shoe on the market because of its emphatic approach towards reducing injury. The Infinity React Run is Nike’s most tested running shoe to date (over 16,000 miles) and was the subject of a unique running epidemiology study by the British Columbia Sports Medicine Research Foundation, which found that the shoe reduced injury rates by a whopping 52% compared to the Structure Triax 22. This finely tuned experiment yielded shockingly positive results for all distance types – not just the marathoners.
Structurally, the Infinity React Run boasts 25% more foam than its predecessor and has a similar wide-base geometry as the aforementioned Vaporfly 4%. The upper consists of an engineered lofted Flyknit built specifically for this silhouette, while the heel-to-toe rocker provides a sensation of propulsion while allowing for quick transition.
