The SHOX R4 is the most beautifully designed athletic shoe ever produced in quantity. The design is made up of an incredible assortment of disparate shapes and structures, yet it's all brought together into a beautifully cohesive whole. Designed by Sergio Lozano, the R4 will have other shoe designers scurrying to catch up for years to come. Also worth noting, of all of the SHOX based shoes, the R4 provides the most noticeable "boing" effect. You can feel it while walking, but you'll really appreciate it when running. The SHOX columns don't propel you upward, they propel you forward, and that's a good thing in a running shoe. VIA: Nike shoes & Jordan shoes
