Call it a gimmick. Call it futuristic. Call it whatever you want, but you can’t say the Adapt BB, isn’t a big swing for Nike in basketball, and in general.

Functional power-lacing is something Nike has been inching towards since it brought the fictional Nike Mag to reality in 2011. They brought it to the masses in 2017 in the HyperAdapt 1.0, albeit at a $700-plus price point at retail, and now the technology officially coming to basketball courts during NBA All-Star Weekend.

“We really took the Adapt BB as a moment to study one of the most intense and rigorous sports that exist,” said Nike senior design director Ross Klein about bringing it to basketball. “Once we knew we could conquer there and know the behavior of a basketball athlete, we could really attack the rest of the environments in sport.”

Basketball isn’t the end for adaptive fit either. There are running and lifestyle versions planned for later this year. In fact, designers were testing the adapt platform on a running version of the sneaker as they were developing the Adapt BB.

Here, Nike’s senior design director breaks down the most important aspects of the Adapt BB.
