The shoe is called the Nike Epic React Flyknit and is a running shoe, which will release on February 22nd. The bottom is a solid piece of foam with a knitted upper, making it lightweight for running. But looking beyond this shoe the technology is likely the start of a new generation of Nike shoes with all-foam bottoms. The foam technology itself is called React and was launched last year in a Nike basketball shoe – but that shoe encased the foam with an outer layer in order to provide the traction and and stability that basketball players require on the court. This new shoe is the first release where the bottom is a single piece of foam without any encapsulation or casing – meaning you’re essentially running directly on a giant cushion.
