Have your little one step with confidence in the Nike Kids' Flex Runner 4 Shoes. Their soft, springy foam in the midsole helps cushion their every step. The flex grooves in the outsole add flexibility, helping every step feel natural, and their multi-surface traction works with sturdy foam that wraps around the heel to provide grip and stability when they shift directions. The pull tabs on the heel and tongue work with a stretchy inner sleeve to help make them easy to put on.
