The 2013 US Open isn’t until August 26th, but Nike is already prepared to show off the special footwear they’ve crafted for the upcoming event. Included in the group are the Nike Air Max Cage, Nike Air Max Court Ballistec 4.3, and the Nike Zoom Vapor Tour 9. You’ll recall that the last of those three was also used for last year’s tournament, which sort of proves how strong Nike is standing behind the silhouette. See the footwear set to be worn by Maria Sharapova, Serena Williams, Victoria Azarenka, Li Na, Roger Federer, Rafael Nadal and Juan Martin del Potro after the jump and stick with us to see if any of the pairs will be hitting retail ahead of the tourney.
