Running shoes made easy! The Nike Flex Runner 2 is for the kid on the go who loves to play all day—from gym class to a sprint down the block. They're lace-free, meaning super quick to slip on and off. Who’s ready to race? Easy On, Easy Fit A stretchy bootie design makes it easy to slip your foot in with a snug and secure feel. A heel strap and leather on the sides stabilize your fit. Fast Steps The flexible foam sole is designed with deep grooves so every step and stride feels secure while running. The sole’s pattern also helps with multisurface traction. Steady Feel The back of the shoe features foam that creates a wing-like shape around the heel for extra stability when moving in different directions.
