The Freeline appear in Wikipedia

Freeline skates are getting every day bigger in the skate world, so now you can find them in the wikipedia. What do you are going to find there?

Freeline skates [wikipedia]: are a kind of skating apparatus ridden like a Snakeboard or Freebord. The skates are not connected to each other and do not have a board, instead relying on the body of the rider. They slightly resemble a skateboard chopped in half with the wheels placed single file behind each other The wheels are angled in such a way that the user's swaying motion moves the skates in a forward direction. This can be used to propel the rider on uphill slants and the skates being independent is a great advantage when carving tight turns that a skateboard couldn't achive.[1]

Freeline skates are only made by their originating company, "Freeline Skates, Inc."
