Almost everyone who sees Back to the Future wants three things: a time-traveling DeLorean, a working hoverboard and a pair of self-lacing shoes. Now, thanks to Nike, the shoe dream is a reality. When wearers press a button near the tongue, the HyperAdapt 1.0s automatically tighten and loosen around their foot. And although this technology may sound frivolous, it’s not just for kicks: simplified shoe fastening could give athletes an edge during competition, and it’s especially useful for people with impaired motor function. “We’re already seeing powerful feedback” from the disabled community, says Tinker Hatfield, Nike’s vice president of design and special projects.
