The Sidewinding Circular Skates consist of a pair of 10-inch rubber wheels with foot platforms. Apart from riding with a sideways stance, the gadget appears to be a futuristic take on roller skates.
Rather than pushing off the ground like a traditional skateboard or skates, the user gains momentum from a Segway-like propulsion by leaning side to side. Braking is achieved by touching one's toes to the ground.
An extendable rod can be attached to offer the rider training wheels of sort.
The separate wheels allow the skater to coast in a weaving motion and lean in to propel forward.
While the Hammacher Schlemmer online catalog is selling the $100 product as "Sidewinding Circular Skates," other tech sites have taken off with the term, "Post Modern Skateboard."
More than a skateboard, though, the contraption might resemble the Heelys from the 2000s. The sneakers that converted into roller skates at the lift of a sole got a bad rap for their hazards to children, which may have cut the craze short.
