Shoe insole and processing method for shoe insole

An insole processing method for making an insole comprising an insole body, said insole body comprising an upper insole layer and a lower insole layer, said upper insole layer comprising a top surface and an opposing bottom surface, the processing method comprising the steps of:

• a) cold pressing said upper insole layer to form a groove on said upper insole layer at a position corresponding to at least one of the heel portion, inner arch portion, outer arch portion, inner metatarsal portion, outer metatarsal portion, inner toe portion and outer toe portion of the structure of the human foot, said groove being located in said bottom surface of said upper insole layer;
• b) bonding said lower insole layer to said bottom surface of said upper insole layer;
• and
• c) performing cold pressing forming;
• wherein in step a), a plurality of grooves are formed in said upper insole layer, and a concave runner is formed between each two adjacent said grooves to connect said grooves;
• wherein before step b), cutting a foam and placing said foam in said concave runner, wherein the foam is located in said concave runner between said upper insole layer and said lower insole layer.

A processing method for making an insole, said insole comprising an insole body, said insole body comprising an upper insole layer and a lower insole layer, said upper insole layer comprising a top surface and an opposing bottom surface, the processing method comprising the steps of:

• a) bonding at least one foam to said bottom surface of said upper insole layer at positions corresponding to at least one of the heel portion, inner arch portion, outer arch portion, inner metatarsal portion, outer metatarsal portion, inner toe portion and outer toe portion of the structure of the human foot;
• b) bonding said lower insole layer to said bottom surface of said upper insole layer;
• and
• c) performing cold pressing forming;
• wherein each said foam has a gap formed therein, said gap defining an air cavity.
