[0002] Injection molded uppers are an important part of injection molded shoes. Through the injection molding process, molten plastic is injected into the mold and perfectly bonded to the upper to form the upper. The materials of injection molded uppers are diverse, and the most common ones are PVC, TPR, PU, etc. These materials give the upper a certain flexibility and elasticity, making the shoes more comfortable and durable.
[0003] After searching, the application with patent number 202420295573.0 discloses an injection-molded shoe with an anti-fouling upper, comprising a shoe, a rubber pad fixedly connected to the bottom of the shoe, a sole fixedly connected to the bottom of the rubber pad, a through groove machined on one side of the inner wall of the rubber pad, a wool layer fixedly connected to the inner wall of the shoe, a silver ion antibacterial fabric layer fixedly connected to one end of the wool layer, an anti-fouling structure provided on one side of the shoe, and a protective structure provided on one side of the shoe;
[0004] Although the injection-molded shoe with a stain-resistant upper is forced to move to the right by the shell, the shell squeezes the rubber block and the ball, thereby playing a buffering role, which is convenient for protecting the toe position and preventing toes from being injured when people kick obstacles. However, the injection-molded shoe with a stain-resistant upper is only provided with a shell at the toe position, which is not convenient for protecting the heel and both sides, and the overall strength of the upper is poor, resulting in the upper being unable to effectively support the ankle.
[0005] Therefore, we propose a thermal insulation injection-molded shoe upper structure. Utility Model Content
