Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a costume style shoe body, and more particularly, to a costume style shoe body which is formed in one piece, fitted, comfortable to wear, fully waterproof and designed with a costume style, and a manufacturing method thereof. 
     2. Description of the Prior Art 
     The development of shoes has been going on for centuries with lots of great designs. In recent years, new shoe types are usually improved models from previous designs with no overall renovations. Therefore, it is common that a shoe design stressed on comfortable features could be inconvenient to wear and lack of esthetic design; on the other hand, a shoe design stressed on convenience could be loose in structure and could be damaged easily. Moreover, a shoe design stressed on multiple functions could have more constructing elements and have more seams in between the elements, making it prone to damaging, inconvenient to repair, and easy to be infiltrated with water. Therefore, such shoe designs are not giving users good wearing experiences. 
     In order to enhance the durability of a shoe body, it is necessary to reduce the number of constructing elements; however, for convenient wearing and comfortable wearing experiences, the traditional shoe design cannot use a one-piece shoe body. 
     Therefore, the present invention discloses an improve shoe body structure, wherein a single shoe material is cut into a shoe surface in one piece to enhance the structural strength and waterproof capability. Besides, the present invention discloses a shoe surface with a fastening portion, which comprises a costume style button or buckle, or a shoe lace of a selected color disposed thereon to enhance the decorative appearance of the shoe design and to make it more popular. Furthermore, the costume style fastening element, such as the button/buckle or shoe lace, can work with the shoe body to provide wearing and decorative functions. 
     In view of the above-described deficiencies of the traditional shoe designs, after years of constant effort in research, the inventor of this invention has consequently developed and proposed a costume style shoe body and a manufacturing method thereof
