Overpronator: Forefoot wear is exclusively under the big toe and ball of the foot area. In severe cases, the wear will be exclusively under the ball of the foot and towards the inside (medial area) of the shoe.
Diagnosis: Because all of the force of the overpronator's weight is directed over the medial/inside portion of the shoe after heel plant, it becomes very important to purchase a shoe with a medial post. The more severe the inside force, the greater the need for a medial post.

Neutral: Forefoot wear is directed straight down the middle of the forefoot. Most of the wear will occur right between the second and third toes.
Diagnosis: These runners can train in just about any shoe design. The medial post is really unecessary.

Underpronator: Forefoot wear is directed primarily towards the outside edge of the forefoot under the pinky toe.
Diagnosis: These runners generally have high arches and rigid feet (meaning they need flexible shoes). Usually, these runners opt for a lightweight trainer because they are flexible and curve lasted (a banana shape) to provide more support under the outside edge of the shoe. Medial posts are again unnecessary.

A footprint with no heel means you’re a forefoot striker.
Diagnosis: You’ll want shoes with cushioning especially at the forefront of the shoe.

A footprint with part of the heel means you’re a midfoot striker.
Diagnosis: You’ll want shoes with cushioning at both the forefront and the heel of the shoe.

A footprint with a predominant heel means you’re a rearfoot striker.
Diagnosis: You’ll want shoes with cushioning especially at the heel of the shoe.
