A reinvigorated midsole construction made from a plush EVA foam makes the Asics GT-1000 13 the most comfortable and energetic version yet in this iconic franchise. For additional stability, the Asics GT-1000 13 features raised medial and lateral sidewalls which keep your child's foot in place by reducing unnecessary side-to-side movements. The solid rubber outsole wraps the medial side of the midsole, increasing durability and support levels.
