Benefits of technology

"The present invention provides an upper for a shoe that is lightweight, soft, durable, and water-resistant. The upper is made of a composite material that includes a fabric layer and an abrasion-resistant coating layer applied to the fabric layer. The coating layer is transparent to allow for easy viewing of the fabric layer. This design provides a comfortable and durable shoe upper that can withstand wear and tear."

Problems solved by technology

For instance, while leather is comparatively soft, it is not water-resistant, and is susceptible to wearing and cracking.
While vulcanized rubber is durable and resistant to water, it is relatively heavy.
As for injected molded plastic materials, they are resistant to water but are not sufficiently durable and soft.
In addition, since surface processing of leather and vulcanized rubber is relatively difficult, uppers made therefrom are rather monotonous in design, appearance and color.
Expensive or time-consuming patterning techniques, such as transfer printing, will be required if patterns are to be formed on such uppers.

Embodiment Construction

[0013]FIG. 1 shows a shoe 100 incorporating the first preferred embodiment of an upper according to this invention. The upper includes a shell body 10 having at least one part made of a composite material. In this embodiment, a toe part 101 and a heel part 102 of the shell body 10 are made of the composite material. Referring further to FIGS. 2 and 3, the composite material includes a fabric layer 11 having an outer surface 111 and an inner surface, and an abrasion resistant coating layer 12 applied to the outer surface 111 of the fabric layer 11. The fabric layer 11 and the coating layer 12 are laminated to each other.

[0014] The fabric layer 11 is made of a material selected from the group consisting of nylon, polyester, polycotton, cotton, acetate, and acrylic, and has a measure of softness so that it is comfortable to wear. In addition, the fabric layer 11 is of such a structure that it readily lends itself to a coloration treatment. The outer surface 111 of the fabric layer 11 ...

Abstract

An upper for a shoe includes a shell body having a toe part and a heel part. At least one of the toe part and the heel part is made of a composite material which includes a fabric layer having an outer surface and an inner surface, and an abrasion-resistant coating layer applied to the outer surface of the fabric layer. The coating layer has a thickness of about 0.05-0.25 mm, and is transparent to permit viewing of the outer surface of the fabric layer through the coating layer.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to an upper for a shoe, more particularly to an upper which is light-weight, soft, and abrasion-resistant. [0003] 2. Description of the Related Art [0004] Materials used for forming uppers of shoes generally include leather, textile fabrics, vulcanized rubber, and various kinds of plastic materials. Among these materials, leather, vulcanized rubber and injection molded plastic materials are generally used for making toe caps and heel cups of shoes for climbing, hiking and hunting purposes, and have their advantages and disadvantages due to their inherent properties. For instance, while leather is comparatively soft, it is not water-resistant, and is susceptible to wearing and cracking. While vulcanized rubber is durable and resistant to water, it is relatively heavy. As for injected molded plastic materials, they are resistant to water but are not sufficiently durable and soft. In addition, sin...
