Hoverboard Dancing Is Basically The New Dancing As These Girls Nail It To Bieber's 'Sorry'

Bieber is going to be 'Sorry' he didn't come up with this.

While we're not even quite sure how to use a hoverboard, these girls are pulling off some amazing moves we've never seen before.

Set to Justin Bieber's hit, "Sorry" the girls from the "Kailey and Kelianne" dance team show us what is really possible when you combine acrobatics and hoverboards.

We already thought dancing was hard enough, but this is seriously taking it to another level.

OK, now they are even synchronized.

That's crazy. OK, while we just try and figure out how to go back and forth, check out the full dance video below.
