Getting the right fit from a performance shoe is both personal and complicated. Consider basketball: Over the course of a basketball game, the foot can expand almost a half-size during play. A level of fit that feels comfortable at one point might feel constrictive just 24 minutes later. Because the needs of the foot change at any given time based on the sport, its duration and on specific movements, like a slashing cut to the basket, "perfect fit" is a floating target. The effort to refine fit has yielded a number of innovative platforms through Nike’s history – Huarache, Flywire and Flyknit, to name a few. Perhaps none was more critical to advancing custom fit than the 2016 introduction of the Nike HyperAdapt 1.0, the first Nike multipurpose performance shoe to feature power lacing. Now, Nike has found its most advanced fit solution to date: Nike Adapt, a platform that creates a truly custom fit by combining an advanced power-lacing system, an app and continually updated firmware, featured in the new Nike Adapt BB basketball shoe. “We picked basketball as the first sport for Nike Adapt intentionally because of the demands that athletes put on their shoes,” says Eric Avar, Nike VP Creative Director of Innovation. “During a normal basketball game the athlete’s foot changes and the ability to quickly change your fit by loosening your shoe to increase blood flow and then tighten again for performance is a key element that we believe will improve the athlete’s experience."
