Next, the cutting department precisely cuts upper materials according to approved patterns. The cut pieces move to the stitching line, where skilled workers sew the upper components together and attach logos, labels, and decorative details.
The completed uppers are then sent to the lasting and assembly line. Here, the upper is shaped over the shoe last and securely bonded with the outsole using professional cementing and pressing equipment. Depending on the construction, additional curing or finishing processes are completed to improve durability.
Every pair undergoes quality inspection, including checks for appearance, sizing, bonding strength, stitching quality, and comfort. Only products that meet the required standards proceed to the final stage.
Finally, the sneakers are cleaned, packed, and cartonized according to customer requirements before shipment. With strict quality control throughout every step, factories can efficiently produce large-volume sneaker orders while maintaining reliable quality, competitive lead times, and customer satisfaction.
