With Nike's NanoPly overlay utilized on the upper, accounting for a more natural sock-like feel, the Swoosh now presents its Spring/Summer 2013 range of the Free 4.0 v2. The lightweight upgrade is appropriately presented in a variety of colorful schemes, all of course showcasing the brand's Free sole unit underneath.
