Shox R4 in Black brings back the compressible heel columns that defined early-2000s Nike—springing back with each step for responsive cushioning and energy return, set on a durable textile-and-synthetic upper with laser perforations for ventilation and a circular waffle outsole for grip.
Does the Shox R4's heel technology still work like the original 2000s version? Yes—the compressible Shox heel columns on this Shox R4 deliver the same spring-back energy return the line has always been known for.
