Motion Control: For those severe overpronators or heavy runners with slight to severe overpronation problems. Medial posts are extreme. Most possess technology in the heel and forefoot. Very heavy and not recommended for fast paced training.
Stability: The category of shoe for most runners who overpronate. These shoes feature longer medial posts (some with plastic pieces to enhance this feature), technology in the heel and usually the forefoot.
Core: This category is moderately priced, has a smaller medial post, heel technology and is a great place to start if you're a beginning runner without any history of shoe wear to examine foot plant.
Cushion: This category places a premium on cushioning and has few stability features. These shoes are designed for neutral and underpronation runners who desire a very soft ride.
Lightweight: For those runners who want a different trainer for faster runs or workouts. These are shoe designed for fast training. Wear and support are secondary considerations.
Racing Flats: Designed with one thing in mind, speed. Don't expect long life or support from these models. Minimal design features make these shoes light weight.
