jjjjawnz: Nike Flyknit Trainer - Nike hired a team of computer programmers and engineers to take a machine used to knit sweaters and socks and reengineer it to weave the upper part of a sneaker. Spools of colored polyester yarn are fed into the 15-foot-long machine, which weaves together the top of the shoe and creates a “second skin” with tiny synthetic cables knitted into the weave around the midfoot for support. Very comfy and a pair weighs only 8.4 ounces. ($150)
