Originally released in 1992, the Puma Disc System is still viewed as an innovative alternative to traditional lacing. Designed with the goal of having "the foot and the shoe merge as one unit," the system features a rounded disc that tightens nylon bands when turned, and a quick release tab that loosens the bands when pulled. The Puma Disc Cage "Tropicalia Pack" features the Puma Disc System in a very fresh and floral package. They are available in two colorways and feature a floral design on the upper. You can get this comfortable spring/summer sneaker soon at Sneakerhead.
