Nike Free 4.0 2015 Spring Summer release

The Nike Free 4.0 is back for this Spring and Summer in an array of colors in both speckled and block-colored palettes.

More flexible than the 5.0 and more cushioned than the 3.0, the Nike Free 4.0 Flyknit Men’s Running Shoe unleashes your natural stride with a lightweight, supportive Flyknit upper and a highly flexible, low-profile outsole.

The Flyknit upper seamlessly integrates areas of stretch and structure, providing ultralight support and a contoured fit, while the highly flexible, low-profile outsoles are built for maximum comfort.

The Nike Free 4.0 is a very lightweight minimalist running shoe.
