The GT-4000™ 2 running shoes are one of the most stable ASICS offerings and are recommended for excessive overpronators. This update retains GUIDANCE TRUSSTIC® technology and DUOMAX® technology, but these support pieces have been bolstered together to improve the shoe's already impressive stability. Along with increased support, a reinforced arch wraps the foot over the sole even better to increase stability and comfort. It's also softer in the heel thanks to the sockliner that sits atop a layer of OrthoLite™ foam for improved step-in comfort. If you need a shoe packed with stability, but don't want to give up fit and comfort, the GT-4000™ 2 running shoe is a recommended stability trainer.
