One is the combination of the sole and the strap, and the other is the complete integration of the sole and the strap. The combination structure of the flip-flops is not firm enough, and the strap and the sole may come off or break during long-term wearing and walking. Although the integrated structure of the flip-flops is more reliable, it often needs to be pre-molded and then integrally injection molded, which not only complicates the manufacturing process, but also limits the individual customization of flip-flops. In addition, the traditional injection molded slippers have poor wearing comfort. SUMMARY
