When you combine longboard skateboarding, roller skates, and I guess a monowheel,you get these cool new Sidewinding Circular Skates. This post modern skateboard lets you stand inside two independent rubber skate wheels and doesn't require a push-off since you propel yourself forward simply by leaning side to side. Not only can you do unique 720 degree spins and extreme turns with ease, you can also slip quickly down walkways like a slithering sidewinder and traverse through short grass and dirt surfaces thanks to the big 10" wheels. Obviously, like anything new, these will require a bit of a learning curve to master your balance and riding skills and comes with a handy extendable rod to connect the wheels for extra stability. Check out this VIDEO to see them in action.
