[0019] By adopting the above technical solution, the beneficial effects of the utility model are:
[0020] In this case, the toe reinforcement part, tongue reinforcement part, heel reinforcement part and surface reinforcement part are set on the base layer formed by winding TPU hot melt wire. Among them, the toe reinforcement part and the surface reinforcement part are laid with thicker embroidery ropes to strengthen the toe and surface layer of the base layer. The spacing between the embroidery ropes is set to limit the deformation of the base layer, improve the wrapping support force, and do not affect the breathability of the base layer.
[0021] The tongue reinforcement portion is paved with thinner embroidery ropes, and the embroidery ropes fit closely together, which increases the strength of the tongue, prevents the subsequent tightening of the shoelaces from causing the shoe upper to twist and deform, and also increases the overall wrapping strength of the shoe upper; a first lace hole opened on the tongue reinforcement portion is embroidered with a first embroidery circle around it, which prevents the first lace hole from being torn and deformed under the pulling of the shoelaces.
[0022] The heel reinforcement is fixed to the base layer by gluing or sewing a leather patch. The leather patch completely limits the deformation of the heel portion of the base layer and improves the wrapping support of the upper around the ankle.
[0023] In this case, TPU upper elements are added through thick rope embroidery, thin rope embroidery and leather patches to increase the sense of design and meet consumers' pursuit of trendy uppers.
[0024] A further beneficial effect is that an embroidery layer is also provided on the leather patch to increase the variety of upper elements and enhance the personalization of the upper.
[0025] A further beneficial effect is that the two sides of the front end, the two sides of the middle section, and the two sides of the rear end of the tongue reinforcement part respectively extend toward the surface reinforcement part to form a front extension part, a middle extension part, and a rear extension part. The front extension part, the middle extension part, and the rear extension part are also formed by the first embroidery rope being tightly wound as a whole, which increases the area of the tongue reinforcement part and reduces the overall deformability of the upper, which is beneficial to improving the overall wrapping force of the upper.
[0026] A further beneficial effect is that the leather patch extends toward the tongue opening to form a tongue extension portion, and the tongue extension portion is provided with two second shoelace holes, which is beneficial to increase the shoelace threading area and improve the overall wrapping force of the upper.
[0027] A further beneficial effect is that a toothbrush embroidered patch is arranged on the outer side of the upper on the base layer, and the toothbrush embroidered patch is integrally fixed to the tongue reinforcement part, the heel reinforcement part and the surface reinforcement part. While increasing the types of upper elements, the tightness of the connection between the three parts is also strengthened, thereby improving the wrapping support force of the outer side of the upper and preventing the foot from spraining.
