A foamed shoe material and its blank. The blank of the foamed shoe material includes a blank body and a plurality of pinholes. The blank body includes an outer surface. The pinholes extend from the outer surface of the blank body to the inside of the blank body, and are suitable for the inflow of supercritical fluid. Through the pinholes, the supercritical fluid can quickly diffuse and evenly dissolve in the inside of the blank body through the pinholes, so that the foamed shoe material formed by foaming the blanks is formed It has uniform and dense foaming micropores, which can not only greatly shorten the foaming time, but also achieve the effect of improving cost-effectiveness. |
