Nike | Women's React Infinity Run Flyknit 2 Running Shoes

Advice for Road Runners: The React Infinity Run Flyknit 2 is designed to allow you to run fearless and reduce injury. This lightweight shoe provides non-stop cushioning throughout your run, and reduces stress on the legs for long distance sessions. When tested against Nike’s next most supportive shoe, the React Infinity Run was shown to reduce the chance of injury by 52%. The Flyknit 2 has been updated to be even softer underfoot with an increased stack height for a more plush feel while reducing flex in the ankle. There is a new cushioned heel collar and a highly breathable upper made with Flywire technology. This fabric construction uses Kevlar to provide a knit that offers maximum support and durability.

React foam provides a highly responsive underfoot feel and the midsole design has a wide base providing added stability. The rocker-like design will help the foot transition from heel to toe, making steady runs feel easier and propels tired legs forward at the end of a long run.

The React Infinity Flyknit 2 provides Nike’s best cushioning for longer runs and is the ideal option if you want to reduce stress on muscles and joints during steady paced runs. If you’re looking for a stability shoe for faster paced runs, check out the Air Zoom Structure 23.

Shoe size is a personal preference and everyone's feet are different, but we want to ensure you avoid any pain or discomfort from bruised toenails, rubbing, blistering or pins and needles. Your running shoes should have enough width to allow you to spread your toes and should have some space at the front (we recommend having a half to one thumb's width of space from the end of your longest toe to the front of your running shoes). This usually means that your running shoe will be at least a half size bigger than your regular shoe size though this can vary from brand to brand.
