Description

Technical Field

[0001] This invention relates to an ultralight sports shoe and its thin upper, belonging to the field of sports shoes. Background Technology

[0002] Athletic shoes are professional footwear specifically designed for sports or travel. Their core characteristics lie in their functionality and professionalism, significantly distinguishing them from ordinary shoes. Through cushioning, elasticity, and support, they provide protection and enhance performance during exercise. To improve athletic flexibility and reduce foot burden, athletic shoes are optimized in terms of materials or structure. Existing athletic shoes achieve lightweighting through structural optimization, mainly by thinning the upper or adding perforations. Uppers that are too thin or have too many or too large perforations will reduce the fit and support. For sports that require stability, this can easily cause the foot to slide inside the shoe, increasing the risk of injury. On the other hand, the soles are made by adding grooves or textures. The former will significantly reduce the stability of the sole, resulting in insufficient support for the foot during exercise or walking, while the latter will not be very effective in reducing weight. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide an ultralight sports shoe and its thin upper. This addresses the problem that existing sports shoes achieve lightweighting through structural optimization, primarily by thinning the upper or adding perforations. However, an upper that is too thin or has too many or too large perforations will weaken its fit and support. For sports requiring stability, this can easily cause the foot to slide inside the shoe, increasing the risk of injury. On the other hand, while the sole can be made by creating grooves or textures, the former significantly reduces the stability of the sole, resulting in insufficient support for the foot during exercise or walking, and the latter is not very effective in mitigating these problems.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: an ultralight sports shoe and its thin upper, the structure of which includes an upper body, the toe portion of the upper body being covered with a toe cap, the heel portion of the upper body being covered with a heel cap, and a reinforcing patch connected to both sides of the outer wall of the upper body, the rear ends of the two reinforcing patches extending and surrounding the outer wall of the heel cap to form a connecting portion, the outer wall of the heel cap being provided with an elastic band for binding and fixing the connecting portion.

[0005] Furthermore, to improve the fit, the lower end of the reinforcing patch is bent and attached to the bottom edge of the main body of the shoe upper.

[0006] Furthermore, in order to achieve ultimate lightweight and breathability, the main body of the shoe upper uses a silicone mesh combined with 3D printed support strips, with a thickness of 0.6mm-0.8mm.

[0007] An ultralight athletic shoe includes a thin upper and a lightweight sole. The lightweight sole is connected to the lower end of the thin upper. The lightweight sole includes an outsole, a midsole, a support component, and a flexible pad. The midsole is fixedly embedded in the top surface of the outsole. A groove is longitudinally formed in the middle of the midsole. Cushioning components are provided on both inner walls of the groove. The lower part of the support component is tightly embedded in the groove and completely covers the cushioning components. The upper part of the support component covers the top surface of the midsole. The flexible pad is placed on the top surface of the support component.

[0008] Furthermore, to enhance the strength of the connection, the top edge of the outsole extends with a binding edge that secures the outer side of the bottom of the thin upper.

[0009] Furthermore, in order to improve the support effect, the support assembly includes a support plate fixedly covering the top surface of the midsole and two support pieces symmetrically connected to the left and right sides of the bottom surface of the support plate. The two support pieces are respectively fixedly attached to the inner walls of both sides of the groove and completely cover the buffer assembly on the same side. The bottom surface of the support piece has a reinforcing plate that extends horizontally through the bottom surface of the groove and connects with the outsole.

[0010] Furthermore, for connection and positioning, the bottom surface of the groove is provided with a slot that is compatible with the reinforcing plate.

[0011] Furthermore, in order to provide torsional cushioning when the athletic shoe is subjected to lateral forces, the support plate has wavy or arc-shaped deformation grooves on both sides.

[0012] Furthermore, in order to improve the buffering performance, the buffer component is specifically a honeycomb mesh groove or a diamond mesh groove, with the mesh facing the support sheet.

[0013] Furthermore, in order to achieve lightweight design, the height from the top surface of the midsole to the bottom surface of the outsole is 3cm-5cm, the height from the bottom surface of the groove to the bottom surface of the outsole is 0.7cm-1.2cm, and the width of the groove is greater than or equal to half the width of the outsole.

[0014] The beneficial effects of this invention are: the ultralight sports shoe composed of a thin upper and a lightweight sole ensures that the upper is extremely thin while the outer wall of the upper has a reinforcing patch to improve its support and fit. The grooved midsole in the lightweight sole, together with the outsole and support components, improves the stability of the sole and prevents the foot from lacking sufficient support during exercise or walking.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example 1

[0018] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 This invention provides an ultralight sports shoe and its thin upper technical solution: its structure includes an upper body 11, the toe of the upper body 11 is covered with a toe cap 12, the heel of the upper body 11 is covered with a heel cap 13, and a reinforcing patch 14 is connected to both sides of the outer wall of the upper body 11. The rear ends of the two reinforcing patches 14 extend and surround the outer wall of the heel cap 13 to form a connecting part 15. The outer wall of the heel cap 13 is provided with an elastic band 16 for binding and fixing the connecting part 15.

[0019] The head part 12 and the tail part 13 of the bag are both made of one of the following materials: leather and plastic.

[0020] To improve the fit, the lower end of the reinforcing patch 14 is bent and connected to the bottom edge of the upper body 11.

[0021] The reinforcing patch 14 is made of high-density woven mesh fabric with a mesh count of 110 to 130, which has the advantage of high support. The reinforcing patch 14 is connected to the main body of the shoe upper 11 by adhesive or hot pressing.

[0022] To achieve ultimate lightweight and breathability, the upper body 11 uses a silicone mesh combined with 3D printed support strips, with a thickness of 0.6mm-0.8mm.

[0023] An ultralight athletic shoe includes a thin upper 1 and a lightweight sole 2. The lightweight sole 2 is connected to the lower end of the thin upper 1. The lightweight sole 2 includes an outsole 21, a midsole 22, a support component 23, and a flexible pad 24. The midsole 22 is fixedly embedded in the top surface of the outsole 21. A groove 221 is longitudinally provided in the middle of the midsole 22. Cushioning components 222 are provided on both inner walls of the groove 221. The lower part of the support component 23 is tightly embedded in the groove 221 and completely covers the cushioning components 222. The upper part of the support component 23 covers the top surface of the midsole 22. The flexible pad 24 is provided on the top surface of the support component 23.

[0024] The outsole 21 is made of natural or synthetic rubber, which has the advantages of being slip-resistant and wear-resistant. The midsole 22 is made of EVA or TPU, which has the advantages of cushioning, shock absorption and rebound. The flexible pad 24 is made of silicone and is used to connect with the insole to prevent the support component 23 from hurting the foot.

[0025] In the production of the midsole 22, the main body with grooves 221 is made by injection molding, and then support components 23 are punched on both sides of the inner wall of the grooves 221.

[0026] To improve the strength of the connection, the top edge of the outsole 21 extends with a binding edge 211 that wraps around and fixes the outer side of the bottom of the thin upper 1.

[0027] To improve the support effect, the support assembly 23 includes a support plate 231 fixedly covering the top surface of the midsole 22 and two support pieces 232 symmetrically connected to the left and right sides of the bottom surface of the support plate 231. The two support pieces 232 are respectively fixedly attached to the inner walls of both sides of the groove 221 and completely cover the buffer assembly 222 on the same side. The bottom surface of the support piece 232 has a horizontally extending reinforcing plate 233 that penetrates the bottom surface of the groove 221 and connects with the outsole 21.

[0028] Among them, the support plate 231, support piece 232, and reinforcing plate 233 are integrally molded structures made of carbon fiber. The reinforcing plate 233 is connected to the outsole 21 to form a rigid support platform, which can convert the running impact force into elastic potential energy and release it as propulsion force when leaving the ground, thereby increasing stride frequency and speed. The support piece 232 ensures lightweight while preventing the sole from collapsing irreversibly during exercise by positioning and restricting the groove 221. The support piece 232 ensures that the midsole 22 is subjected to comprehensive forces and prevents excessive deformation of the groove 221.

[0029] Among them, the cross-section of the groove 221 is an isosceles trapezoidal structure, which effectively improves the stability of the structure.

[0030] For connection and positioning, the bottom surface of the groove 221 is provided with a slot 223 that is adapted to the reinforcing plate 233.

[0031] like Figure 5 As shown, in order to provide torsional cushioning when the athletic shoe is subjected to lateral forces, the support plate 231 has wave-shaped deformation grooves 234 on both sides.

[0032] To improve the buffering performance, the buffer component 222 is specifically a honeycomb mesh groove with its mesh facing the support piece 232, which facilitates the punching process.

[0033] For lightweight design, the height from the top surface of the midsole 22 to the bottom surface of the outsole 21 is 3cm-5cm, the height from the bottom surface of the groove 221 to the bottom surface of the outsole 21 is 0.7cm-1.2cm, and the width of the groove 221 is greater than or equal to half the width of the outsole 21. Example 2

[0034] For the sake of brevity, the parts that are the same as those in other embodiments will not be described again. The description will mainly focus on structures that differ from other embodiments of the present invention, such as... Figure 6 As shown, the support plate 231 has arc-shaped deformation grooves 234 on both sides to improve the structural stability of the support plate 231 after torsion and reset. Example 3

[0035] For the sake of brevity, the parts that are the same as those in other embodiments will not be described again. The main focus here is on the structure that is different from other embodiments of the present invention. For ease of processing, the buffer component 222 is specifically a rhomboid mesh groove.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
