1. A shoe with a step counting capability, comprising:

  • a shoe body adapted to be worn on a foot of a wearer, said shoe body including a vamp and a sole mounted on said vamp, said sole including an outer sole portion which has a top side formed with a receiving space, and an inner sole portion which is disposed on top of said outer sole portion;

    a step detector disposed in said receiving space, said step detector including a piezoelectric unit which generates a voltage output when subjected to impact, and an impact unit which is disposed adjacent to said piezoelectric unit and which is associated operably with said inner sole portion so as to impact said piezoelectric unit every time the foot of the wearer raises then lowers said shoe body for stepping on a ground surface;

    a transmitter device disposed in said receiving space and connected electrically to said piezoelectric unit, the voltage output from said piezoelectric unit serving as a power input of said transmitter device and activating said transmitter device to radiate a radio frequency signal; and

    a receiver device for receiving the radio frequency signal from said transmitted device and for counting number of times the radio frequency signal was received thereby so as to generate a step count output.
