The production process of genuine leather insoles mainly includes the following steps:
Raw material preparation: The main raw material of genuine leather insoles is leather, usually top layer pigskin, lambskin, cowhide, etc. These leathers need to be strictly selected and inspected to ensure that the quality meets the requirements.
Cutting: According to the size and shape requirements of the insole, the leather is cut into appropriate shapes and sizes. This step requires precise measurement and cutting techniques to ensure that the insole fits the shoe perfectly.
Stitching: The cut leather pieces are stitched together by sewing machine or by hand to form the basic shape of the insole. When stitching, attention should be paid to the uniformity and firmness of the stitches to ensure the durability of the insole.
Processing: In order to increase the comfort and durability of the insole, some special treatment may be required. For example, the leather surface can be frosted to increase friction and prevent sliding; or waterproof treatment can be performed to improve the waterproof performance of the insole.
Quality Inspection: After production, the insoles are strictly inspected to ensure that every detail meets the standards. This includes checking the firmness of the stitching, the quality of the leather, and the overall comfort. Packing and Shipping: Finally, the qualified insoles are packaged, usually in transparent plastic bags or cartons to ensure that they are not damaged during transportation and storage. The packaging will be marked with information such as brand and model to facilitate consumer identification and purchase.
