Disclosed herein is a functional shoe, capable of applying micro current to the sole. The shoe includes a micro-current generating part, an acupressure part, and a conduction part. The micro-current generating part is inserted in a side of the shoe, thus generating predetermined micro current and voltage. The acupressure part is made of a conductive material, and is provided on a portion where nerve points of a sole connected to organs in a body are located, thus simultaneously performing physical acupressure action and conduction of micro current. The conduction part is connected between the micro-current generating part and the acupressure part, thus transmitting the generated micro current and voltage to the acupressure part. Thereby, the functional shoe simultaneously performs physical acupressure action on specific nerve points of the sole, and transmits micro current to the nerve points using external force applied when walking.
