I was curious so I did some research and came across a company called freeboardstore.com. They sell complete boards (decks, wheels, trucks, and bindings) starting at $220. A great way to practice switch during the off season!
I think I'm on their site right now looking at how they work. Caster wheels between skate wheels? [B]Ingenious.
Years ago I had a caster board, which was apparently supposed to be "just like snowboarding". - I call BS!
It had several problems:
1.) It was too short for me.
2.) I couldn't rock heelside to toeside; it was this weird...squirrelly motion which was stupid.
3.) Worst problem: It was just balanced on 2 caster wheels and was ridiculously easy to come off it. I couldn't land jumps, slide, or come to a sudden stop and easily lost control at high speeds.
These freeboards, however, look awesome!
