FLEXIBLE COMFORT. Nike Flex Experience RN 8 Men's Running Shoe delivers snug, dynamic comfort on your run—and beyond. Mesh around the heel along with flex grooves in the outsole encourage a natural ride that adapts to your every step. Knit fabric conforms to your foot for a snug feel. Rounded heel promotes a natural range of motion. No-sew overlay at the laces and toe tip adds durability. Injected unit sole (IU) midsole provides a resilient ride and enough durability to double as an outsole. This allows for a reduction in rubber and overall weight. Hexagonal flex grooves are hot-knife cut to offer 6 different flex points for natural motion. Textured outsole provides additional traction and durability.
