Feet are classified into three different styles (Balance, Inner and Outer). Each has a different running pattern and requires a different shoe style.
Balance
For this stride, the heel hits the ground first, then the forefoot and toes. Thus, the entire weight of the body is evenly distributed on the feet. The recommended shoe for runners with this stride is a balance shoe with better heel cushion and center support.
Deviation in
For this stride, the inner heel hits the ground first, followed by the big toe. The feet roll in during running, making it more difficult to stabilize the body. The recommended shoe for runners with this stride pattern is stability or motion control.
Outward deviation
External deviation is the opposite of internal deviation. In this case, the outer heel hits the ground first, followed by the little toe and the foot pointing outward. The recommended shoe for runners with this stride is one that has cushioning and provides quick (flexible) heel-to-toe force.
