In the '90s, running shoes were reborn with fit systems. The PUMA Disc, part of the Trinomic family, was sought after for its comfort-boosting clicks. (Twist it and internal wires tighten the upper for a fit that's just right. Pull the tab to loosen and remove.) Today?

It also opts for fresh cage details; they channel Brasil's street status symbols, carats, and cool with a metallic finish.
