The difference between cold adhesive shoes and injection molded shoes

Production process:

Cold adhesive shoes: Using adhesive to connect the upper, insole, and outsole together, it is usually considered handmade and needs to be processed on an assembly line.

Injection molded shoes: After the shoe upper is placed on an aluminum last, materials such as PU (polyurethane) are usually directly injected by a turntable machine, and the molten material is injected into the outer mold and bonded to the upper as a whole.

Appearance features:

Cold adhesive shoes: Heels or edges usually have no lines, soles are flat, and there are no injection holes.

Injection molded shoes: There will be a line on the heel or edge, which is the mark left when the shoe is molded.

Material usage:

Cold adhesive shoes: glued together with glue may not be waterproof, and the benzene in the glue can cause certain harm to the human body.

Injection molded shoes: Most of them are made of PU material, which is uniform and corrosion-resistant. The sole and upper are not glued together.

Price and cost:

Cold adhesive shoes: usually priced higher because of their small daily production, suitable for medium-sized and above factories to form a scale of production.

Injection molded shoes: Affordable because the production process reduces a lot of labor and the output is large.

Product features:

Cold adhesive shoes: may be more refined, but the sole and upper are prone to delamination.

Injection molded shoes: Excellent quality, not easy to open glue, sole resistant to breakage, wear-resistant, waterproof, low-carbon and environmentally friendly.

In summary, there are significant differences between cold adhesive shoes and injection molded shoes in terms of production process, appearance, material use, price, and product characteristics. The choice of which type of shoes depends on individual needs, budget, and expectations for shoe quality and appearance.
