The sole is defined with a concave, and close to a middle of both lateral edges of the sole is formed a protruding portion, respectively, a bottom of the sole is an arc-shaped surface. The toe post has one end integrally formed with the concave, and a head portion at the other end of the toe post has a larger diameter than the post portion. The vamp has two ends integral with the protruding portions of the sole and is located around an outer periphery of a rear half of the sole, an engaging portion extends from the inner edge to near a center of the vamp, the vamp can be folded upward over the sole from its two ends connected to the two protruding portions so as to make the toe post engage in the engaging portion.
