Overview
The Nike ReactX InfinityRN 4 is a well-cushioned and stable running trainer, although it may lack the lively energy return of some other running shoes. The latest iteration introduces a new ReactX midsole, which offers enhanced softness and comfort, albeit at the cost of a slightly increased weight. While it may not be the most responsive shoe, it's well-suited for easy and recovery runs.
The Nike Infinity series has seen various changes throughout its history, from claims of injury reduction to its role as a daily training shoe with a rocker design and heel clip for mild guidance. The InfinityRN 4 represents a significant shift in the series, with a fully maximal design. The shoe features a new knit upper for added space and a substantial amount of ReactX foam in the midsole, providing a cushioned and rockered ride for longer distances. This new foam is notably soft and bouncy, offering a comfortable yet stable experience. It's a shift away from Nike's older React foam, resembling New Balance Fresh Foam in terms of cushioning. Despite its softness, it maintains a decent level of stability, making it a suitable choice for runners seeking a plush and comfortable ride.
According to our analysis of reviews from experts around the world, it averages a review score of 78%. This puts it in the lowest rated 30% of comparable running shoes. According to our analysis of prices across the internet, at current rates it's in the most expensive 40% of running shoes.

In Depth
Upper
The upper of the Nike InfinityRN 4 is made of a soft, stretchy Flyknit material, providing a snug fit.

The shoe also features a water repellent liner in the toe box, adding an extra layer of protection.

Comfort
The InfinityRN 4 is a comfort-centric shoe. The tongue is optimally cushioned and the heel tab is convenient. However, the upper's tendency to run warm and absorb sweat might affect overall comfort.
