Abstract
Description
Technical Field
[0001] This utility model relates to the field of footwear technology, specifically to a shoe that increases speed. Background Technology
[0002] Common shoes typically consist of a sole, insole, upper, tongue, and laces. Each time shoes are put on or taken off, the laces need to be properly tied and the tongue wrapped inside the upper, which takes time. Furthermore, due to the material or tying method of the laces, they can easily come loose, potentially leading to falls, trips, or other accidental injuries, increasing the likelihood of injury. Utility Model Content
[0003] This invention provides a shoe that increases the speed of wearing shoes, overcoming the shortcomings described in the background art.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] A type of height-increasing shoe includes an upper, a sole, an inner height-increasing main heel, and an insole. The upper and sole are connected to form the shoe. The bottom of the heel area of the insole is nested onto the inner height-increasing main heel. The inner height-increasing main heel includes a wrapping surface and a height-increasing sole. The wrapping surface and the height-increasing sole are integrally formed and are both made of elastic material.
[0006] A preferred technical solution: The shoe has an elastic opening.
[0007] A preferred technical solution: A tongue area is provided on the shoe, and the upper uses elastic shoelaces to tighten the tongue area. The elastic shoe opening, elastic shoelaces, and inner heel wedges work together to achieve a height-increasing effect while improving ease of wear.
[0008] A preferred technical solution: The shoe adjusts the three-dimensionality of the upper by using an inner last. The last helps the upper material maintain its shape during the manufacturing process, ensuring a neat appearance after the shoe is formed. The shape of the last determines the internal space and fit of the shoe. By using the last, the shoe matches the foot shape, reducing compression or looseness, and reducing friction and discomfort.
[0009] A preferred technical solution: The elastic material is TPU (thermoplastic polyurethane), which is durable and elastic, used to stabilize the heel and provide support.
[0010] A preferred technical solution: The elastic material is EVA (ethylene-vinyl acetate copolymer), which is lightweight and has good elasticity, providing good shock absorption and support.
[0011] A preferred technical solution: A padding layer is provided on the inside of the shoe upper, and the wrapping surface of the inner heel is built into the padding layer.
[0012] A preferred technical solution: wrapping the wrapping surface with filler.
[0013] A preferred technical solution: The filling material is sponge, memory foam, or latex. Sponge filling is lightweight and soft, providing basic cushioning and comfort, and is commonly used in casual and athletic shoes. Memory foam filling molds to the shape of the foot, providing personalized support and comfort, and is mostly used in high-end athletic and casual shoes. Latex filling is soft and elastic, suitable for shoes with high comfort requirements.
[0014] A preferred technical solution: The insole is a height-increasing insole.
[0015] By adopting the above technical solution, the beneficial effects of this utility model are:
[0016] The height-increasing shoes of this invention achieve internal height increase through a height-increasing sole, and can be stacked with height-increasing insoles to achieve the same effect. When worn, the force exerted by the foot on the inner height-increasing main heel causes the wrapping surface of the main heel to undergo elastic deformation. The main heel deforms downward and outward, driving the elastic shoe opening to enlarge it, making it easier for the foot to enter the shoe cavity. Then, the inner height-increasing main heel returns to its original shape, wrapping the foot, while the elastic shoe opening also shrinks and returns to its original shape. With the combined action of the inner height-increasing main heel and the elastic shoe opening, the foot is less likely to slip off during walking. Attached Figure Description

[0024] like Figures 1-4 As shown, a type of height-increasing shoe includes an upper 1, a sole 2, an inner heel lift 3, and an insole 4. The upper 1 and the sole 2 are connected to form a shoe. The bottom of the heel area of the insole 4 is nested onto the inner heel lift 3. The inner heel lift 3 includes a wrapping surface 31 and a height-increasing sole 32. The wrapping surface 31 and the height-increasing sole 32 are integrally formed and are both made of elastic material.
[0025] Furthermore, the shoe has an elastic opening (55).
[0026] Furthermore, a tongue area 11 is provided on the shoe, and the upper 1 is tightened by elastic shoelaces 6 to adjust the tightness of the tongue area 11. The elastic shoe opening 5, elastic shoelaces 6, and inner heel wedge 3 work together to achieve a height-increasing effect while improving wearing convenience.
[0027] Furthermore, the shoe adjusts the three-dimensionality of the upper 1 through the inner last 7. The last helps the upper 1 material maintain its shape during the manufacturing process, ensuring that the shoe has a neat appearance after molding. The shape of the last determines the internal space and fit of the shoe. The last makes the shoe match the foot shape, reducing compression or looseness, and reducing friction and discomfort.
[0028] Furthermore, the elastic material is TPU (thermoplastic polyurethane), which is durable and elastic, used to stabilize the heel and provide support.
[0029] Furthermore, the elastic material is EVA (ethylene-vinyl acetate copolymer), which is lightweight and highly elastic, providing excellent shock absorption and support.
[0030] Furthermore, a padding layer is provided on the inner side of the upper 1, and the wrapping surface 31 of the inner heel 3 is built into the padding layer.
[0031] Furthermore, the wrapping surface 31 is surrounded by wrapping filler.
[0032] Furthermore, the filling material can be sponge, memory foam, or latex. Sponge filling is lightweight and soft, providing basic cushioning and comfort, and is commonly used in casual and athletic shoes. Memory foam filling molds to the shape of the foot, providing personalized support and comfort, and is often used in high-end athletic and casual shoes. Latex filling is soft and elastic, suitable for shoes with high comfort requirements.
[0033] Furthermore, insole 4 is a height-increasing insole.
[0034] During the wearing process, the force exerted by the foot on the inner heel 3 causes the wrapping surface 31 of the heel to undergo elastic deformation. The heel deforms downward and outward, driving the elastic shoe opening 5 to enlarge the shoe opening, allowing the foot to smoothly enter the shoe cavity. Then, the inner heel 3 returns to its original shape, wrapping the foot and achieving the purpose of quick wearing. At the same time, the elastic shoe opening 5 also shrinks and returns to its original shape. Under the combined action of the inner heel 3 and the elastic shoe opening 5, the foot will not slip off during walking.
[0035] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
