Nike Shox Rival R3 Men's Running Shoes Detailed Information Nike Shox technology is re-owned for its ability to provide extreme cushioning and stability to the feet. Shox are small hollow columns that make up the midsole of the shoe. This "Shox" technology is especially useful for sports where there is high impact between the feet and the ground. The principle behind Shox technology is simple. When the heel strikes the ground, the Shox columns absorb the energy of the strike and compress like a spring which bounces back and returns the energy to the wearer as they transfer their weight to the forefoot in preparation for the next stride. The Nike Shox Rival R3 features a great, lightweight, breathable fit, and is designed for the runners in need of maximum cushioning and impact protection. It comes with dust bag and shoebox.
