New in box - Women's Size 9 Smoke free home! These are SO GREAT for either running or for high impact workouts including weightlifting. Cannot recommend these enough! PURE GRAY 3 / PURE GRAY 5 / CORE BLACK Reebok’s Nano X1, “the Official Shoe of Fitness,” continues the Nano series tradition of pushing boundaries and redefining what an all-purpose cross-training shoe can do. Built for any type of movement, this latest design introduces a new, softer Flexweave knit construction with a comfort collar, delivering all-day breathability and locked-in wearability with no break-in time required out of the box. The Nano X1 also features an updated toe shape for freer multi-directional movement, an improved heel clip for max stability, and new Floatride Energy Foam in the forefoot for better run cushioning. These new developments, combined with classic Nano features and style, put the X1 at the forefront of both durability and versatility, equally suited for sprints, squats, climbs, box jumps, and everything in-between.
