Nike is on a more than 50-year mission to make the best fitting shoes. And senior design director Ross Klein thinks Nike's new, self-lacing smart shoe, the Adapt BB, is a step in the right direction. "Not only is it the engine, and not only is it the type of cord that we are using, but it is also the materials that we are pulling around. All of that is generating the best fit we've ever produced in basketball," Klein told Cheddar.
