From running to climbing the playground, the Nike Flex Runner makes everything easy. The slip-on design plus strap-in feel means you can forget the laces (for now!). Add in a foam sole that's super-duper flexible so every step, stride and jump is as easy as 1, 2, 3. Stretchy and breathable fabric hugs your feet to help them feel cool and comfy. The super flexible foam sole has grooves so every step and stride feels natural. Fabric & leather upper Slip-on Round toe Synthetic lining Cushioned footbed Foam midsole Flexible injected foam unit sole Both of these were worn a lot but you get what you pay for because these are still in fantastic shape. They matched my Nikes so “mommy and me” pics were always fun. He used to get complements on these constantly and I always felt good about him having quality, supportive shoes on while his feet still developed. 😍. Very easy to slide on! I am selling the exact same pair in size 6 and 7!
