Recovery allows the body to recharge and refuel so you are better prepared for your next workout. Without proper rest, you deny your body the chance to adapt to the stress it has endured during a run and the gains your body has made during it. By wearing OOFOS after a workout, you jump starts the recovery period by absorbing the impact your body would otherwise undertake.
When you take the proper time to recovery, you are able to go into your next workout stronger and better equipped to conquer your next goal.
