The Nike React Infinity Run was first introduced in 2019.

It was designed to help reduce injury and keep you on the run. The lightweight and flexible upper details, higher foam stack heights with wider shape, provided a secure and cushioned yet responsive feel. The rubber on the outsole also delivered good traction and durability.

In 2020/2021, Nike launched the Nike React Infinity Run Flyknit 2, which continues to help keep you running. A refreshed upper uses Flywire technology that combines with Flyknit for support and breathability where you need it. The high foam heights provide soft responsiveness and long-lasting comfort.

Design & Comfort


The Nike React Infinity Run Flyknit 2 features an advanced Flyknit upper which provides good breathability and ventilation, while keeping your foot secure with its strength and durability. The Flywire technology also offers extra support and stability through the midfoot.

The plush and responsive feel from the React foam remains in this new edition. There is an improved fit with added padding on the tongue and collar, and the flywire lacing structure.

The toe box remains roomy and stretchy too.


The rounded midsole gives the same rocker geometry to the Nike React Infinity Run Flyknit 2. This encourages a slight lean forward, moving a runner’s foot strike from heel to midfoot, or even forefoot, creating a natural forward feel of propulsion. The wider platform and supportive foam provide a reassuring feel, gently guiding the foot in a smooth, straight line, reducing side-to-side wobbling and movement.

There is only a slight weight increase over the 1st edition, which I think is contributed by the added padding. However, this does not affect the overall performance of the shoes.


The Nike React Infinity Run range is a good absorber of running impact on the joints. This is a recommended daily trainer which is comfortable and durable, while remaining responsive.

Nike React Infinity Run Flyknit 2 is available in Singapore via for S$239.
