The Asics GT-1000 running shoe packs performance, fit and cushioning into a sleek profile. Mild-to-moderate overpronators will enjoy this replacement of the GT-2170 mile after comfortable mile. Breathable, seamless, lightweight upper. SpEVA midsole with heel and forefoot Gel Cushioning Systems takes the shock during impact and allows movement in multiple planes as the foot moves through the gait cycle. DuoMax dual-density foam support system on the medial side helps prevent overpronation. Discrete heel unit controls torsional movement between the forefoot and rearfoot and mimics the connective tissue of the foot by returning energy as the foot moves through its stride. Full-length Guidance Line improves gait efficiency. DuraSponge in the forefoot is made from a blown AHAR compound, for responsive cushioning and flexibility. Wt. 10.4 oz.
