Stability trainers are designed for a runner who pronates past the point of neutral. This is known as overpronation, and these shoes are designed with supportive features in the midsole (specifically under the arch area) of the shoe for runners who mildly or moderately overpronate. The technology in stability shoes helps bring the foot into a neutral alignment to reduce the risk of injury. If you’re not sure, why not call in to store for a free gait analysis to ensure you're running in the right trainers. Your gait can change over time so it's worth getting a regular check up.
