The Nike Shox R4 is the original Nike Shox running model, and sprung on to the scene in 2000. They were constructed with innovative Shox technology, which was inspired by the remarkably springy indoor running track at Harvard. Small high-density PU Foam columns in the heel were designed to absorb impact from heel strike during athletic activities, and "spring back" to add more power to your stride. A wide array of Nike sneaker models use Shox technology today, but the original models were the R4 runner, BB4 court sneaker, and the XT4 cross-trainer.
Overall Rating for Nike Shox R4
Jake, Chicago, IL
This shoe has a great way of centering your balance. You never feel like you are about to fall over and its does a good job of transferring impact energy into your next stride. Great quality of materials and very comfortable on the feet. Also, great barefoot as well - great shoe with a great look!!
