The Nike Flex Runner 3 Baby/Toddler Shoes are built for active little ones with an easy slip-on design and multi-surface traction to keep up with every adventure. A stretchy bootie provides a snug, sock-like fit, while synthetic leather overlays, a reinforced toe, and a heel strap offer added support and durability. Foam wraps the heel for extra stability during quick moves, and flex grooves in the outsole help every step feel smooth and natural. Breathable mesh keeps the shoe lightweight and cool, and handy pull tabs on the heel and tongue make on-and-off a breeze for both kids and parents.
