NATURAL FROM HEEL TO TOE. Nike Flex 2015 Running Shoe delivers a natural feel in a sleek design. Up top,the forefoot stretches for toe splay, while a tighter mesh through the midfoot offers support. Underfoot, the tri-star pattern works with the rounded heel design to adapt to your every step.
Soft foam wraps the heel for a secure, dynamic fit.
Grooves in the outsole let the pistons expand and contract, promoting flexible, natural motion.
Rubber pods add traction and durability in high-wear zones.
