Foot type: The category into which a particular foot falls. Foot types are generally classified into one of three categories: pronator, neutral, or supinator.
The supinator type of foot restricts the impact of the stride largely to the outer edges of the foot. This is often due to a very high, rigid arch.
The neutral type of foot is between the pronator and supinator types. It is the most common foot type. Runners with a neutral type of foot lands on the heel and rolls forward during the gait cycle until the impact is distributed evenly across the forefoot.
