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 δ [−20° C.], a loss factor at 25° C. is tan δ [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 ηmin, and the maximum value thereof is ηmax, in a dynamic viscoelasticity measurement: 1≤tan δ [−20° C.]/tan δ [25° C.]≤5 . . .  (1); 50 MPa≤E′ [25° C.]≤400 MPa . . .  (2); 0.05 MPa·s≤ηmin . . .  (3); and ηmax≤0.6 MPa·s . . .  (4).
