The Normal Foot Normal feet have a normal-sized arch and will leave a wet footprint that has a flare, but shows the forefoot and heel connected by a broad band. A normal foot lands on the outside of the heel and rolls inwards slightly to absorb shock. It's the foot of a runner who is biomechanically efficient and therefore doesn't need a motion control shoe.
Best shoes: Stability shoes with moderate control features.

The Flat Foot
This has a low arch and leaves a print which looks like the whole sole of the foot. It usually indicates an overpronated foot - one that strikes on the outside of the heel and rolls inwards (pronates) excessively. Over time, this can cause many different types of overuse injuries.
Best shoes: Motion control shoes, or high stability shoes with firm midsoles and control features that reduce the degree of pronation.

The High-Arched Foot
This leaves a print showing a very narrow band or no band at all between the forefoot and the heel. A curved, highly arched foot is generally supinated or underpronated. Because it doesn't pronate enough, it's not usually an effective shock absorber.
Best shoes: Cushioned or Neutral shoes with plenty of flexibility to encourage foot motion.
