Nike has unveiled a lookbook for the Summer 2015 Track & Field Collection, celebrating four decades of their running heritage. It features modern sportswear silhouettes that blend transparency and mesh, offering breathable and lightweight summertime expressions. When creating the pieces, the design team studied local run crew culture from around the world, drawing inspiration from their diligence and dedication. Whether they were out for a run or meeting with friends, members of these crews were always on the move from dusk until dawn. The bright colors in the pack signify that the sun never sets on a runner’s day. In addition to the apparel, the range includes the Free Viritous, the Free Socfly and the Air Rift. The Nike Track & Field Summer 2015 Collection is available now on Nike.com. Turn the page to take a look.
