Yes, you can run with it. However, the power generation efficiency depends on your form. Our device is designed to capture the force created by your heel. A heel strike running form is considered to be incorrect and even unhealthy. The two recommended forms are a midfoot and forefoot strike. Your heel does absorb some impact in a midfoot strike and thus you will generate power. In a forefoot strike, where your heel never touches the ground, you will not generate power.
