A combined shoe formed by a selected vamps and soles with different functions and appearances at any time, comprises a sole, a vamp and attaching means used to quick-connect the vamp and the sole for forming a whole shoe. The attaching means includes a front cap located in front of the sole for buckling the tip of the vamp; a hind cap located in the hind of the sole for buckling the heel of the vamp; two pairs of matched anti-slide plates located in half-soles/heels of both vamp and sole for preventing relative sliding between the vamp and the sole; and a plurality of pressing means used for pressing the vamp on the sole tightly. The combined shoes provide a multitude of combinations and reduce the shoe purchasing cost. Since the vamp and the sole can be disassembled and assembles quickly, when the wearer enters a room, he needs only remove the sole for keeping the cleanliness of the room and still can keep his feet warm and/or prevent the diffusion of foot odor.
