Shark Wheels were invented and started up by David Patrick and really challenged the status quo of the circular wheel. The Shark longboard wheels roll all the way from OC, California and are a combination of sphere and cube. In that way, they can get the maximum out of the properties of both shapes.
The Shark skateboard wheels have a sine wave pattern which has a thinner contact patch with the surface. This automatically means less friction and respectively, more speed. In addition, they allow better manoeuvrability, performance, and durability in conditions like water, debris, and dirt which normally is a problem for conventional circular wheels.
