Learn moreRunning shoes made easy! The Nike Flex Runner 2 is built for the kid on the go who loves to play all day—from PE to a sprint down the street. They're lace-free, meaning they're super quick to slip on and off. Who's ready to race?
.
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 stabilise your fit.
.
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 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.
