Abstract: Provided is a method for manufacturing a porous midsole the method including: a cotton-beating step (S1) of forming a midsole base (10) having porous voids 16 by mixing low melting fibers (12) and high melting fibers (14); and a thermoforming step (S2) of bonding and fixing the high melting fibers into a compressed state by the melt adhesive strength of the low melting fibers (12) by compressively thermoforming the midsole base (10) at a melting point temperature of the low melting fibers (12).
