Abstract
A combined structure of a sports shoe and an in-line skate mainly comprises an in-line wheel device buried in the shoe bottom of a sports shoe. The in-line wheel device comprises a base, whereon a linkage set, a position plate, a wheel position mechanism and a torsion spring are combined in order at both sides by position pins and shaft bars and arrangement at each side is homologous with the other side such that wheels are set among two sides and arranged in in-line state. Besides, a control mechanism is combined to the rear of the base and can control wheels to be unfolded and taken in automatically such that the shoe body combined with an in-line wheel device can take wheels in the sole ordinarily for walking and running, and unfold wheels automatically when the user wants to take skating sport.
