ABSTRACT:
An EVA insole manufacturing process includes a step of mixing an EVA resin with a foaming agent for producing a molding through an injection molding process, and a step of heating the molding thus obtained in a mold so that it foams into a predetermined shape. Two or more moldings which respectively contain a different concentration of foaming agent or a different pigment color may be put together in a common mold and subjected to integral foaming and form setting process, so as to produce an insole which has different hardness and color at different parts thereof.
