Lighter than ever before, the Nike Free Flyknit 4.0 Running Shoe takes a model you love and throws in Flyknit material for the ultimate in breathable lightweight running performance. Add in Flywire cables and you've got a running shoe that gives you plenty of suppot and comfort without adding extra bulk.

The barefoot-like feel you expect from Nike Free is still present in this model, but the addition of Flywire and Flyknit elevates it to must-have status.

Drop the extra weight and enjoy total comfort on the run in the Nike Free Flyknit 4.0.
