Overview

Chapters

• 00:00 - 00:30: Introduction to Athletic Shoes Athletic footwear has origins in ancient history, but the modern concept became popular with the invention of treaded rubber soles in the early 20th century. These shoes, known as sneakers for their quiet tread, have evolved in design, increasing their popularity.
• 00:30 - 01:00: Cutting Patterns for the Upper This chapter explains the process of cutting patterns for the upper part of athletic shoes. It highlights how a hydraulic press is used to force a dye through synthetic fabric to create these patterns. Additionally, there is a focus on the punching out of leather toe tips, which are among several cutouts that contribute to the shape and structure of the shoe's synthetic upper.
• 01:00 - 01:30: Stiffening the Toe Tip A worker arranges tip parts on a non-stick tray and places strips of thermal resin onto them. A nonstick sheet is draped over the tray before it's placed into a hot metal press. In the press, the resin melts into the leather to stiffen and strengthen it. Following this, another worker stamps the model number onto the heel cut out.
• 01:30 - 02:30: Sewing Department Operations The chapter titled 'Sewing Department Operations' focuses on the sewing department's role in assembling athletic shoes. It describes how a worker stitches a reflector onto the shoe upper and explains the need for more intricate stitching on accent pieces. The worker uses a computerized platform that automates the movement, ensuring precise stitching that would be challenging to achieve manually.
• 02:30 - 03:30: Assembling the Upper The chapter titled 'Assembling the Upper' details the process of assembling the shoe's upper part. It begins with sewing a reflective logo onto the shoe using computer-guided software. Next, a resin-fortified leather toe tip is attached. Finally, the chapter describes how the collar is pieced together and sewn to the back of the shoe, completing the assembly for this part of the shoe.
• 03:30 - 04:30: Adding Structure to the Shoe The chapter titled 'Adding Structure to the Shoe' describes the process of installing thick foam padding on the inside of a shoe collar. After installing, the collar is turned right side out to neatly tuck the padding inside and hide the seams. Once the collar is in place, any obscured lace holes are cleared using a compressed air punch. Additionally, further down in the production line, computerized needles are used, indicating advanced technology in the shoe manufacturing process.
• 04:30 - 05:30: Bonding Upper to Sole This chapter describes the process of assembling an athletic shoe, specifically focusing on the sewing of brand information onto the tongue panels, adding liners and padding, and stitching a fabric base onto the shoe. The sequence emphasizes working inside out to conceal seams.
• 05:30 - 06:30: Final Assembly and Inspection In the chapter titled 'Final Assembly and Inspection,' the process of assembling the shoe is detailed. A piece of rigid plastic is applied to the heel of the shoe to provide structure and support. This is followed by the shoe being placed on a foot form called a 'last,' which helps shape the shoe. Heat is applied to make the shoe malleable, allowing a machine to mold it to the shape of the last. Additionally, nozzles apply cement to the shoe for gluing purposes.
• 06:30 - 07:00: Feedback and Suggestions The chapter discusses the process of bonding the upper part of a shoe to the rubber sole. Initially, heat is applied to both the upper and the rubber sole, activating the glue on the sole and preparing the upper for bonding. Manual force is initially used to press the two components together. Following this, the shoe is placed in a machine where mechanized pressure is applied via an expanding rubber bladder to ensure a secure bond.
