Original Mens Nike Flex 2017 RN Running Grey Platinum Black 898457 002 Size UK 10.5 (SA 10.5)

Adaptive fit. Zoned support. 

Top to bottom the Men’s Nike Flex RN 2017 Running Shoe is built to flex. Its one-piece engineered mesh upper, adaptive heel design and molded tri-star outsole pattern work together for a smooth ride that moves with your stride. 

Dynamic Flywire cables provide a 1:1 fit. Engineered mesh provides breathable support. Tri-star outsole pattern enhances flexibility. Co-molded midsole uses a softer injected Phylon (IP) core foam directly underfoot and a slightly firmer injected unit sole (IU) carrier foam to deliver comfort and durability for a smooth ride. Heel is rounded for a smooth transition at initial touch down. 

Flywire helps provide ultra-lightweight support and comfort for your foot. It gets its strength from thin Nylon fibers strategically placed on the upper of the shoe to hold the foot in place, helping to reduce slippage during activity. This allows for a massive reduction in weight because material is used only where it’s needed for structure.
