In this preferred embodiment, the sole 2 has an internal circumferential surface 23 at the groove portion 22 extended from the sole 2 to the protruding circular portion 21, and the decoration ring 3 has an external circumferential surface 31 coupled with the internal circumferential surface 23 of the sole 2, and the decoration ring 3 is clamped between the sole 2 and the body 1 and attached along the top rim of the protruding circular portion 21 correspondingly.

In this preferred embodiment, the decoration ring 3 has a circular strip 32 connected to the top rim of the protruding circular portion 21, and the circular strip 32 is substantially a circular cross-section.

With reference to FIG. 3 for a cross-sectional view of a decoration ring 3 fixed between the sole 2 and the body 1 in accordance with the present invention, the decoration ring 3 can be formed (by an injection molding) at a desired position of the sole 2, and then the body 1 is adhered or sewed onto the sole 2 to constitute the shoe structure of the invention. Of course, the decoration ring 3 can be formed onto the body 1 first, and then the shoe is combined with the sole 2.

With reference to FIG. 4 for a manufacturing method of a lightweight shoe with a decoration structure in accordance with the present invention, the method comprises the steps of:

Forming a sole 41 by a foaming material in a mold: manufacturing a sole 2 by a foaming material in a mold, wherein a protruding circular portion 21 is integrally formed upward from the top of the sole 2, and a groove portion 22 is formed in the protruding circular portion 21 of the sole 2;

Manufacturing a color decoration ring 42: manufacturing an integrally formed color decoration ring 3 by polyvinyl chloride (PVC), thermoplastic rubber (TPR) or thermoplastic polyurethane (TPU);

Manufacturing a body 43: forming a wearing space 11 recessed from the top of the body and corresponding to the shape of a foot, and defining the bottom of the wearing space 11 of the body 1 as a closed bottom 12; and
