The lasting process involves stretching the upper over a mold, called a last, which defines the shoe’s shape. The upper is then secured to the last, typically using tacks or staples. This step is critical for ensuring the shoe’s fit and form. Different lasting methods, such as hand-lasting and machine-lasting, are used depending on the shoe’s complexity and the desired quality.
Attaching the Sole
The sole is attached to the lasted upper using various methods. These include:
- Cementing: Gluing the sole to the upper, a common method for many types of shoes.
- Stitching: Sewing the sole to the upper, providing enhanced durability and a premium look.
- Vulcanization: Bonding the sole to the upper using heat and pressure, often used for rubber soles.
- Injection Molding: Injecting molten material (like polyurethane) into a mold to form the sole, directly attaching it to the upper.
The chosen method depends on the shoe’s design, materials, and intended use.
Finishing and Inspection
After assembly, the shoe undergoes finishing and inspection to ensure quality and appearance. This stage involves trimming excess materials, adding finishing touches, and inspecting for any defects.
Trimming and Detailing
Excess materials, such as excess glue or threads, are trimmed. The shoe may also be subjected to additional detailing, such as burnishing the edges of the sole or applying protective coatings. These finishing touches contribute to the shoe’s overall aesthetic appeal and durability.
Quality Control and Inspection
Each shoe is inspected for any defects, such as imperfections in the stitching, sole attachment, or material quality. Quality control checks are performed throughout the manufacturing process to minimize defects. Any shoes that fail to meet the required standards are either repaired or rejected.
