Doctor Approved Built with a durable design for kids' everyday activities, from the schoolyard to the playground, the GT-1000™ PS (Pre-School) shoe draws inspiration from our line of performance running shoes.Constructed with a mesh upper, this shoe improves air circulation to keep feet cool, while the removable insole is accented with a printed toe line so kids and parents can check the shoes are the right fit. Thanks to a more sustainable design approach, this shoe also uses fewer resources when coloring the insole.The midsole is layered and combines EVA foam with cushioning based on GEL™ technology, for a more responsive stride and better shock absorption.Additionally, the outsole is paired with a stitched toe cap and rugged rubber compound for added durability.
