Normally, when you hear about a social media challenge, you start to worry about what kind of dangerous situation your kids could be getting into.
Relax. The only warning we've got for you with the #VansChallenge is that you might find a lot of shoes lying around the house.
It started with a video from someone who said that Vans shoes will always land facing up. It was followed by thousands who tried it and swear by it... then by those who debunked it.
THEN they switched to Crocs.
What's next?
Uh... guess you'd have to say we're waiting for the other shoe to drop.
