Flip-flops, also known as thong sandals, are simple footwear produced through a straightforward process. First, raw materials like rubber, PVC, or EVA foam are prepared for the sole, while straps are made from plastic, fabric, or leather. The sole is molded using heat and pressure, creating a cushioned base. Next, the straps are attached by inserting them into pre-cut holes in the sole and securing them with small knots or adhesive. Some flip-flops feature decorated straps or patterned soles for style. After assembly, the sandals undergo quality checks for durability and comfort. Finally, they are packed and shipped to retailers. The entire process is efficient, making flip-flops affordable and popular worldwide.
