<p>A dual-purpose shoe includes an outsole having increased thickness for forming two open-bottomed cavities. In each of the cavities, there is mounted a wheel assembly that includes a fixing bracket screwed to a top of the cavity, a wheel holder movably mounted in the fixing bracket, a wheel rotatably supported on the wheel holder, and a pair of control plates fixed at two sides of the fixing bracket to connect at an end to the wheel holder. The control plates of each of the wheel assemblies mounted in the cavity are connected to an external knob. Turning the knob clockwise or counterclockwise causes the control plates to pivotally turn and thereby bring the wheel holder to move upward or downward in the fixing bracket. When all the wheel holders are moved upward, the wheels retract into the cavities and the shoe functions like an ordinary shoe, and when the wheel holders are moved downward, the wheels expose from the cavities and the shoe functions like a roller skate. <IMAGE></p> |
