PURPOSE:To produce a core material for shoes which is formed by a so-called direct soling for molding a shoe bottom by injection or filling and integrating it with a vamp part, and suitably used for heel stepped shoes. CONSTITUTION:A core material 1 for shoes consisting of a shank part 2 and a heel core part 3 which are integrated together and an upper surface form according to a middle bottom upper surface form is buried in an injected or filled shoes bottom material, and integrated with shoes. The shank part 2 and the heel core part 3 have holes 5, 6, 6' for passing the shoes bottom material. The diameter 51 opened on the middle bottom lower surface side of at least the hole 5 of the shank part is set larger than the diameter 52 opened on the other side, the heel core part 3 has a hollow part 4, and the heel core part 3 is constituted into a two-stage thickness structure so that the rear end part is thicker than the front end part. |
