09 Nike Shox R4 Black+Pink Logo Women Dream Lover Shoes
Nike Shox R4
Nike Shox sprung on to the scene in 2001. The unique Shox technology
was inspired by the remarkably springy indoor running track at
Harvard. Small hollow columns make up the midsole and are mostly made
of rubber. And, Nike states that these columns not only absorb impact
from heel strike during athletic activities, but they also "spring
back" and 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.
