Following the release of its Back to the Future-inspired sneaker, Nike is set to put out a commercially available self-lacing shoe called the HyperAdapt 1.0 in December. The shoe uses sensors to detect the wearer's foot and laces automatically to adapt. Tiffany Beers, a senior innovator at Nike, told Wired in September that the shoe needs a three-hour charge to run for about two weeks. In Nike's own words, the sneaker boasts an "unprecedented level of comfort," which sounds a little kinky in a good way.

We have a few questions about these shoes, which will sell for $720 at Nike's 45 Grand space in New York.

What happens when the battery dies? Do you become trapped in the shoe?

Can the shoe trace your steps?

Is there an "analog" option for people who feel nostalgic?

Can they alert you about dangerous terrain ahead?

What happens if you step in a puddle?

Can you put more than just feet in the shoe?
