Abstract: There is provided an outsole for shoe in which air circulation and impact absorption are simultaneously achieved, which is comprised of a space (140) formed between an elastic plate (114) of an upper sole (110) and an upper surface (122b) of a bottom sole (120), the elastic tubes (116) vertically arranged and installed in the space, and an adhesive sheet (130) which closes each bottom hole (116b) of the elastic tubes (116) and is fixed to the upper surface (122b) of the bottom sole (120), which has effects that the elastic plate (114) is repeatedly pressed and restored or the elastic tubes (116) are repeatedly deformed and restored so that air within the space (140) is discharged through the vent holes (114a) to ventilate the inside of shoes, that the entire soles of feet have acupressure applied by the elastic tubes (116) maintaining the shape, and that an impact applied to a human body is softened by the elastic tubes (116) deformed and restored.
