Description

Technical Field

[0001] This utility model relates to the field of sports shoe technology, and more specifically to a lever-assisted, effort-saving sports shoe with a multi-hardness zoned midsole. Background Technology

[0002] Athletic shoes are shoes designed and manufactured based on the characteristics of people participating in sports or travel. The soles of athletic shoes are different from ordinary leather shoes or rubber shoes; they are generally soft and elastic, providing a certain degree of cushioning, enhancing elasticity during exercise, and some can even prevent ankle injuries.

[0003] However, most existing athletic shoe midsoles use a single material or a uniform hardness design, resulting in low energy return efficiency and insufficient arch support when the foot strikes the ground. In addition, the traditional sole upturn design fails to effectively utilize the body's center of gravity transfer characteristics during walking, leading to high energy loss and foot fatigue. Utility Model Content

[0004] Based on the above problems, this utility model provides a lever-assisted, effort-saving sports shoe with a multi-hardness zoned midsole.

[0005] The present invention adopts the following technical solution: A lever-assisted, energy-saving athletic shoe with a multi-hardness zoned midsole includes a sole and an upper. The sole is an arc-shaped sole with both ends raised. The sole consists of a midsole and an outsole from top to bottom. The midsole is composed of three independent parts: a forefoot area, a midfoot area, and a heel area. The hardness of the forefoot area, midfoot area, and heel area is different. The midfoot area is located below the arch of the foot in the midsole and is the softest.

[0006] Furthermore, the forefoot area is the main component of the midsole, extending from the forefoot to the heel, and the bottom of the forefoot area is provided with a first mounting part for mounting the midfoot area.

[0007] Preferably, the mid-waist area extends from the arch of the midsole to the heel, the top surface of the mid-waist area is mounted on the first mounting part, and the bottom surface of the mid-waist area is provided with a second mounting part for mounting the heel area.

[0008] Preferably, the heel area is located at the heel of the midsole, and the top surface of the heel area is mounted on the second insert.

[0009] Furthermore, the hardness of the forefoot area is greater than the hardness of the heel area, which is greater than the hardness of the midsection area.

[0010] Preferably, the hardness of the forefoot area is Shore hardness 60-70C, the hardness of the midfoot area is Shore hardness 30-40C, and the hardness of the heel area is Shore hardness 40-50C.

[0011] Furthermore, the mid-waist area is made of nylon-fiberglass composite sheet, and the flexural strength of the nylon-fiberglass composite sheet is ≥100MPa.

[0012] Furthermore, the heel area is made of shock-absorbing material.

[0013] Furthermore, the outsole is a rubber outsole, and the bottom surface of the outsole is provided with wear-resistant and anti-slip textures.

[0014] Furthermore, the upward angle of the sole is 15° to 30°, and the upward angle of the heel of the sole is 15° to 30°.

[0015] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: The sole of this invention features an arc-shaped design with both ends raised. The midsole is composed of three independent components with different hardnesses. When worn, it optimizes gait by utilizing the characteristics of human walking. The midfoot area strikes the ground first to deform and store energy, and then the center of gravity shifts forward, releasing elasticity in the midfoot area. The forefoot's raised shape further assists in propulsion, generating a seesaw-like propulsive force. By utilizing the principle of leverage, it achieves effortless walking and reduces foot fatigue. Attached Figure Description

[0016] Figure 1 This is the front view of the present utility model.

[0017] Figure 2 This is the front view of the sole of the shoe according to this utility model.

[0018] Figure 3 This is an exploded view of the sole of the shoe according to this utility model.

[0019] The parts labeled in the diagram are: sole 10, upper 22, midsole 11, outsole 12, forefoot area 111, midfoot area 112, heel area 113, first insert part 31, and second insert part 32. Detailed Implementation

[0020] The specific implementation of the present invention will now be described with reference to the accompanying drawings.

[0021] Reference Figure 1 and Figure 2 A lever-assisted, energy-saving athletic shoe with a multi-hardness zoned midsole includes a sole 10 and an upper 20. The upper 20 of this invention is basically the same in design as the upper 20 of existing athletic shoes, and will not be described in detail here. The sole 10 is an arc-shaped sole 10 with both ends raised; the forefoot upturn angle of the sole 10 is 15°–30°, and the heel upturn angle of the sole 10 is 15°–30°.

[0022] Reference Figure 2The sole 10 comprises a midsole 11 and an outsole 12 from top to bottom. The midsole 11 consists of three independent parts: the forefoot area 111, the midfoot area 112, and the heel area 113. The hardness of the forefoot area 111, midfoot area 112, and heel area 113 varies. The midfoot area 112 is located below the arch of the foot and is the softest. Specifically, the hardness of the forefoot area 111 is greater than that of the heel area 113, which is greater than that of the midfoot area 112. Preferably, the hardness of the forefoot area 111 is Shore A hardness of 60-70C, the midfoot area 112 is Shore A hardness of 30-40C, and the heel area 113 is Shore A hardness of 40-50C.

[0023] Reference Figure 2 and Figure 3 Furthermore, the forefoot area 111, as the main component of the midsole 11, extends from the forefoot to the heel. The bottom of the forefoot area 111 has a first mounting portion 31 for mounting the midfoot area 112. Viewed from the width direction of the sole 10, the first mounting portion 31 presents a U-shaped recessed groove structure. The forefoot area 111 is primarily used for propulsion, providing propulsive force, and has the highest rigidity.

[0024] Reference Figure 3 The midsole section 112, serving as the second main component of the midsole 11, extends from the arch of the midsole 11 to the heel. The top surface of the midsole section 112 can be glued to the first mounting part 31. The bottom surface of the midsole section 112 has a second mounting part 32 for mounting the heel section 113. Viewed from the width direction of the sole 10, the second mounting part 32 presents a U-shaped recessed groove structure. The midsole section 112 is primarily used for contact deformation and energy storage, and is preferably made of nylon-fiberglass composite sheet with a bending strength ≥100MPa.

[0025] Reference Figure 3 The heel area 113, as the third main component of the midsole 11, is located at the heel of the midsole 11. The top surface of the heel area 113 can be installed on the second mounting part 32 by means of shoe glue. The heel area 113 is mainly used for shock absorption and energy absorption, and is preferably made of shock-absorbing material.

[0026] Outsole 12 is an all-rubber outsole with wear-resistant and anti-slip textures on the bottom surface. Outsole 12 can be installed on the bottom surface of midsole 11 by adhesive.

[0027] Reference Figures 1 to 3The sole 10 of this invention is an arc-shaped sole with both ends raised. The sole 11 is composed of three independent parts with different hardness: the forefoot area 111, the midfoot area 112, and the heel area 113. This allows the athletic shoe to optimize gait when worn and walked. The mechanism is as follows: When walking, the midfoot area 112 touches the ground first. The nylon-fiberglass composite sheet of the midfoot area 112 is the softest and deforms first to store energy. The heel area 113 then touches the ground to absorb shock. Subsequently, the body's center of gravity shifts forward, the hard area of ​​the forefoot area 111 presses down on the ground, the nylon-fiberglass composite sheet of the midfoot area 112 releases elasticity, and the forefoot elevation of the forefoot area 111 assists in the propulsion, generating a seesaw-like propulsive force. By utilizing the principle of leverage, it achieves effortless forward movement, optimizes gait, and reduces foot fatigue.

[0028] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
