The Nike Flex Experience RN 8 delivers lightweight comfort that conforms to your every step. Soft knit material hugs your foot, while grooves in the outsole encourage a flexible feel that's ready for wherever your route takes you. The hexagonal flex grooves offer 6 different flex points for multi-directional foot movement while the knit fabric conforms to your foot for a snug feel. The soft mesh in the heel gives an adaptive fit and the midsole provides a resilient ride and enough durability to double as an outsole. This allows for a reduction in rubber and overall weight.
