A stretchy bootie design makes it easy to slip little feet in with a snug and secure feel. A midfoot strap, a heel strap and leather on the sides stabilizes the fit. The flexible foam sole is designed with grooves so every step feels natural. The sole’s pattern also helps with multi-surface traction. The back of the shoe features foam that creates a wing-like shape around the heel for extra stability when moving in different directions. Breathable fabric on the front of the shoe is lightweight and helps keep feet cool. The toe tip is reinforced for extra durability for toe-draggers. Pull tabs on the heel and tongue help make the shoe easy to take the shoe on and off. Nike Flex Runner 2 is built for the kiddo on the go who loves to play—from the playground to wherever their day takes them. It’s laces-free! Meaning it’s super quick to slip on and off. The straps and bootie-like design make sure your little one’s fit stays snug while they run and jump.
