Laminate for laser bonding, shoe, and method for producing shoe

A method for producing a shoe, comprising the steps of:

• preparing a laminate in which a first member formed of a thermoplastic foam, a bonding sheet that is melted by irradiation of laser light, and a second member having transparency to laser light are laminated in this order, with the difference between the melting point of the first member (Mfoam) and the melting point of the bonding sheet (Msheet) (Mfoam−Msheet) being −50° C. to 20° C. and the difference between the melt viscosity of the first member (Vfoam) and the melt viscosity of the bonding sheet (Vsheet) (Vfoam−Vsheet) being 3.0×105 Pa·s to 8.0×105 Pa·s;
• and
• bonding the first member and the second member together with the bonding sheet interposed therebetween by irradiation of laser light from above the second member of the laminate.
