A pair of men's nike shox R5 running shoes in black and silver .
Do you know how the nike shox system works? I can tell you. When you are doing some sports, the Shox is absorbing energy from impact of the wearer?? heel and then returns the stored energy as you moves forward. I must say the Nike Shox R5 technology does a better job to returning the energy transferred to it than the Air Max shoes. You do not have to jump high, you do not have to run very fast, as long as you love moving, playing, this retro running shoes will make you become the coolest person.
