  • Patent number: 10159309
    Abstract: A vamp with loop protection eyelets and a manufacture method thereof are disclosed. The vamp comprises a vamp body including a middle part having a notch which functions as a shoe tongue part. The vamp body is one-piece knitted fabric or a sheet-splice-vamp. Strings are projectively fixed on the upper surface of the vamp body. Threads embroider and fix the strings on the vamp body along a path of the length direction of the strings. The strings not only form a pattern on the vamp body but also leave loops on the shoe tongue part. Loops protrude inwards from both side edges of the shoe tongue part. The vamp has ventilation and has good supportability and straightness, is not only esthetic but also can protect feet. Protection eyelets are connected very firmly and do not come off easily. The pattern with a stereoscopic visual effect is formed on the vamp.
