Everyone always says that nothing in life comes free, but you beg to differ. Nothing compares to the liberating feel of taking to the open road in the Nike Free Run+ 2. What can you say? Some things in life really are just priceless . Update to the Nike Free Run+, SKU#7618866. An ideal running shoe for a wide range of runners. It provides the strengthening and natural gait management benefits associated with barefoot training, while offering the necessary cushioning, traction and underfoot protection. Combination mesh and supportive synthetic leather uppers are both lightweight, yet hardy. An innovative design bonds narrow strips of the two materials together in key support areas, increasing durability and eliminating excess material. Asymmetrical lacing minimizes pressure over the top of the foot for increased comfort. Lightly padded tongue and collar for added comfort and support. Innersleeve envelops the entire foot for a glove-like fit. Molded insole offers great step-in feel, heightened comfort and support. Phylite midsole is highly resilient and durable enough to double as an outsole, drastically reducing the overall weight. Ultrahigh resolution siping pattern promotes an exceptionally smooth, naturally neutral ride. Center-of-pressure heel construction delivers cushioning upon impact without affecting flexibility or transition. Abrasion resistant BRS 1,000 carbon rubber for heightened durability in high-wear areas. Waffle pistons on the outsole work in conjunction with the Phylite midsole by absorbing impacting shock, while being resilient enough to return to their original shape. Strategically placed segments of solid rubber enhance traction in high-wear areas. Measurements: ; Weight: 9 oz ; Product measurements were taken using size 9.5, D - Medium.
