The present invention pertains to: a foam marble composition for shoes; and a method for producing same. More specifically, the present invention pertains to a foam composition for shoes, the foam composition being obtained by mixing a base resin and a color pigment resin. The base resin is obtained by mixing an additive with a resin containing: 95-100 wt% of an ethylene vinyl acetate copolymer (EVA); and 0-5 wt% of a polyolefin elastomer (POE) or low-density polyethylene (LDPE) as a resin modifier. The color pigment resin contains 0-5 parts by weight of a filler, 0-1 parts by weight of an active agent, 0-3 parts by weight of zinc oxide, 0-1 parts by weight of a crosslinker, 0-3.5 parts by weight of a foaming agent, and 0.5-4 parts by weight of a pigment, with respect to 100 parts by weight of any one or two or more selected from the group consisting of a polyolefin elastomer (POE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE), styrene-ethylene-butadiene-styrene (SEBS), and ultra-high molecular weight polyethylene (UHMW-PE). The foam composition contains 90-95 wt% of the base resin and 5-10 wt% of the color pigment resin. The color pigment resin, which has a softening point that is 20-40°C higher than that of the base resin, is mixed with the base resin to perform foaming at a temperature between the melting temperature of the base resin and the softening temperature of the color pigment resin, such that the base resin melts and the color pigment resin having a high softening point and melting point does not melt. Thus, mixing of the base resin and pigment is prevented, such that a clear and beautiful marble pattern is formed on shoe insoles, midsoles, and unit soles.
