A material made up of strong yet lightweight strands of yarn that have been woven into a one-piece upper, securing an athlete's foot to the shoe platform.

Breathability. The Flyknit lets in a lot of air and my feet felt as cool as possible given the hot summer weather. The breathability is right in line with similar Flyknit models so it translates well to running.

Our verdict. The React Infinity Run Flyknit 3 from Nike is the brand's easy-day running shoe. With a generous cushion, we found it comfortable to eat up lots of miles on the pavement. And if you're looking for a lockdown fit that will keep you stable from the first stride to last, this shoe won't disappoint.

We recommend the Nike Free RN NN as an excellent choice for: Runners with a neutral stride who prefer lightweight and agile daily trainers with a bare-there ride. forefoot/midfoot striking runners who want a flexible mid-drop road shoe that can bend it like Beckham.
