Abstract: Provided is a shoe sole member that is partially or entirely formed from a resin foam product constituted by integrating of resin foam particles, wherein the resin foam particles are composed of a resin composition containing a polyamide elastomer, and the resin foam product satisfies all formulas (1) to (4) below, when a loss factor at ?20° C. tan ? [?20° C.], a loss factor at 25° C. is tan ? [25° C.], a storage elastic modulus at 25° C. of the resin composition is E? [25° C.], the minimum value of a complex viscosity at 100° C. to 130° C. of the resin composition is ?min, and the maximum value thereof is ?max, in a dynamic viscoelasticity measurement: 1?tan ? [?20° C.]/tan ? [25° C.]?5 . . .??(1); 50 MPa?E? [25° C.]?400 MPa . . .??(2); 0.05 MPa·s??min . . .??(3); and ?max?0.6 MPa·s . . .??(4).
