Problems solved by technology

[0016] The enamel layer can be provided only on the necessary part of the surface of the outsole that has not been vulcanized by rubber. After the rubber is vulcanized, it is bonded with the upper leather and the midsole to form a shoe. Cracks occur on the enamel layer on the surface of the outsole, and parts with insufficient ozone resistance

Abstract

The invention provides a shoe in which a large sole is adhered to a vamp or middle sole of the shoe under the condition that one part of the large sole is elongated, wherein, only by arranging resin coating film on the surface and the circumference of the elongated large sole, ozone resistance is excellent, and appearance and design of the shoe are not reduced. The shoe of the invention is formed at least by the shoe vamp and the large sole made of rubber containing double bond in molecule main chain, the shoe is provided with an extension part adhered with the shoe vamp and other parts under the condition that one part of the large sole is elongated, and the resin coating film is arranged on the elongated part and only the surface at circumference of the elongated part.

Description

technical field [0001] The present invention relates to a shoe, wherein the outsole is formed of natural rubber or synthetic rubber having double bonds at least in the molecular main chain, and in a state where a part of the outsole is elongated, the adhesion to the shoe upper or other parts is improved. The ozone resistance of the connected part. Background technique [0002] In ordinary shoes, natural rubber and synthetic rubber are mostly used for the outsole, so that the anti-skid property, rebound property and processability are excellent. Such soles include a type formed of only an outsole; a type in which a sole is formed by stacking a multilayer structure of a midsole and the like formed of a material different from the outsole, and the like. [0003] Such sole and upper leather are joined to make a shoe. [0004] The process of manufacturing shoes includes: a method of vulcanizing the rubber after joining the sole and the upper; a method of joining the upper and t...
