Nike's $350 "Adapt BB" sneakers are the latest in the company's line of self-lacing shoes, and they come with the "Nike Adapt" app for Android and iOS. The app pairs with the shoes and lets you adjust the tightness of the laces, customise the lights and see, uh, how much battery life your shoes have left.
However, Nike's Android app is borked, and Android users report that their new kicks aren't paring with the app properly.
Some customers report failed firmware updates for the shoes, which render them unable to pair with the app at all. "My left shoe won't even reboot." writes one owner.
Unfortunately for most users who have been moaning on Twitter, there is not a hell of a lot of sympathy for those who spent $350 on a bunch of useless trainers.
Had it been $1,200 for a pointless mobile phone they might have got a little more sympathy.
However, we now live in a world where people can brick their shoes or suddenly find our feet are security threats.
