Nike's React Infinity Run is fine-tuned for a combination of stability and maximized cushioning to help reduce runner injuries. Unveiled in January 2020, this edition is engineered with a Flyknit bootie for a secure fit, neon collar trim and a unique lacing system. Gradient overlays on the counter hold revamped Swooshes. Supported by a Pink Blast heel clip, the widened React foam midsole offers smooth transitions on top of full outsole tread.
