My idea is about a free-time transport equipment. It is mostly like a rollerskate but the wheels are designed differently. It can be used either on asphalt, or on dirt. The idea\'s great innovation is in the wheels\' placement. Their location is outside the feet (the diameters are 270 millimeters long). The wheels are covered with impregnated tires. The supports are three cones each supplied on rollers.
In the shoes the horizontal movement of the feet is limited.
