Nike Women's Reactx Infinity Rn 4 Shoes - Maximum Cushioned Run

Our review of the Nike Women's Reactx Infinity Rn 4 Shoes finds them best suited for runners and everyday wearers who prioritize cushioning and all-day comfort. The single biggest reason to buy is the updated ReactX foam platform that delivers exceptionally high cushioning without feeling sluggish, making long runs and long days on your feet notably gentler. The shoes also add an updated Flyknit upper and an enhanced toe box for a snug, secure fit, plus a waterproof membrane that keeps feet dry in wet conditions.

Key Features

• ReactX Foam: Provides an exceptionally high level of cushioning and a soft, curved platform that smooths each step for long runs or extended wear.
• Updated Flyknit: Offers a comfortable, supportive knit that hugs the foot while allowing enough flexibility for natural movement.
• Enhanced Toe Box: Gives extra room and protection at the front of the shoe to reduce pressure and improve durability during road running.
• Waterproof Membrane: Keeps feet dry in wet weather, extending usability beyond dry conditions and protecting the foam and knit.
• Snug Collar and Tab: Creates a secure, sock-like fit around the ankle that minimizes hot spots on longer outings.

Who It's For

These shoes are ideal for road runners who want maximal cushioning and a plush ride, and for people who spend long hours on their feet and need robust comfort and support. The waterproof membrane also makes them a good choice for commuters or anyone who faces light wet conditions but still wants a soft running platform.

Runners seeking a minimalist, highly responsive shoe or those with wide forefeet should look elsewhere, as feedback on fit is mixed and some users report the shoe runs small or feels tight in the toe area. If precise race-weight performance is your priority, a lighter, less-cushioned model will be a better match.

Pros & Cons
