How do Orbitwheel Skates work?

[Vaer]

I've been researching skates and boards the last few hours and came across these Orbitwheel Skates.

I am completely baffled by how the wheel mechanism in these things works. The website says very little about them and I've not been able to track down anything else.

So I thought I'd sign up here and see if anyone has any ideas

PS: Most comparisons I've seen say the Freeline skate design is better, sturdier, faster, cooler, etc.

Hi Vaer

Looks to me that the grey outer that you place your feet in stays stationary and inside the grey outer, there is a red inner which rotates on a bearing.
Look closely on the you tube video and you will see what I mean.
