The Cardiff Skate Company unveiled a new type of skate at the ISPO 2014 in Munich (Germany). This model has three 100 wheels: one on the front and two on the sides. The fourth wheel on the rear is a brake. The frame of the skate is adjustable and you can use your own shoes with it.
Lift the heel for braking: the rear wheel will touch the frame and the ground at the same time, providing a smooth braking (as on a scooter).
The concept is fairly manageable despite its three wheels. We suggested to the manufacturer to add an additional strap on the instep to get a better control/support.
