[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] I. Working principle of the present invention:

[0024] A high-tech functional shoe for enhancing and restoring knee joint function according to the present invention mainly consists of a sole 1, a shoe upper 2, a shoe vamp 3 and an insole 4. The shoe upper 2 is located above the sole 1 and serves to connect the sole and the shoe vamp and wrap the side of the foot; the shoe vamp 3 is located above the shoe upper 2 and is used to protect the upper part of the foot and provide a certain degree of breathability; the insole 4 is located inside the shoe upper 2 and above the sole 1, which is the key design part of the present invention.

[0025] At least one counterweight 5 is provided at the bottom of the insole 4, and the counterweight 5 is fixedly or detachably connected to the insole 4. The counterweight 5 is a lead block, which has a relatively high density and can provide sufficient weight in a relatively small volume. And the shape of the counterweight 5 is consistent with the shape of the insole 4 to ensure uniform distribution of weight at the bottom of the insole and avoid excessive local pressure affecting wearing comfort.

[0026] In one embodiment, a plurality of counterweights 5 are provided, and the plurality of counterweights 5 are arranged in parallel and are adhesively connected between the counterweights 5. This connection method can ensure the stability between the plurality of counterweights and is convenient for assembly during the production process. The insole 4 is made of memory foam material. Memory foam has good elasticity and conformability, can be adaptively adjusted according to the shape of the foot and the pressure distribution, provides a comfortable foot feeling, and is adhesively connected to the counterweight 5 to ensure close combination of the two and fix the position of the counterweight on the insole.

[0027] In another embodiment, there is one counterweight 5, and its shape is the same as that of the insole 4. The insole 4 is made of pure cotton material, which has good moisture absorption and breathability, and can keep the feet dry and comfortable. An opening 401 is provided at the bottom of the insole 4, and the counterweight 5 is arranged at the bottom of the insole 4 through the opening 401. This design facilitates the installation and replacement of the counterweight, and users can adjust the weight of the counterweight or replace the counterweight with different materials according to their own needs.

[0028] In addition, a lace 301 is provided on the upper surface 3. The lace 301 can be adjusted according to the width of the foot and the needs of the wearer, so that the shoes fit the feet more closely during wearing, and prevent relative displacement between the shoes and the feet during walking or exercising, which may affect the wearing experience and function.

[0029] The principle of the present invention is based on the principles of human movement mechanics and rehabilitation medicine. When the wearer puts on this functional shoe, the counterweight at the bottom of the insole will increase the overall weight of the shoes. During walking or exercising, the leg muscles need to overcome this additional weight to move, thereby stimulating the muscle groups around the knee joint, including the quadriceps femoris and hamstring muscles. For example, in actions such as lifting the leg and taking a step, the muscles need to output greater force, and long-term use can promote the exercise of these muscles and enhance muscle strength.

[0030] According to the principles of biomechanics, the increased weight will change the distribution of the human body's center of gravity and the force-bearing conditions of the lower limbs. When standing, the weight of the counterweight causes the pressure distribution of the feet on the ground to change, and then through the conduction of the lower limb bones and joints, a moderate pressure stimulus is generated on the knee joint. This pressure stimulus can promote the secretion and circulation of synovial fluid in the knee joint, help maintain the nutritional supply of articular cartilage, and reduce joint wear. During exercise, such as walking and going up and down stairs, due to the presence of the counterweight, the flexion and extension movements of the knee joint will be subject to certain resistance, which requires the muscles and ligaments around the knee joint to work together to enhance the stability and coordination of the joint. At the same time, this moderate resistance training conforms to the principle of progressive resistance training in rehabilitation medicine, and can gradually improve the function and adaptability of the knee joint, which has a positive effect on the rehabilitation and prevention of knee joint diseases.

[0031] II. Embodiment:

[0032] 2.1. Embodiment 1:

[0033] The sole 1 is made of rubber material with good wear resistance and elasticity, and is injection molded through a mold to ensure that the sole has an appropriate thickness and pattern to provide sufficient friction and support.

[0034] The shoe upper 2 is made of leather material, which has a certain strength and flexibility, can effectively protect the side of the foot and is firmly connected to the sole.

[0035] The upper 3 is made of a combination of breathable mesh fabric and leather. The mesh part ensures the breathability of the shoes, and the leather part enhances the abrasion resistance and stability of the upper.

[0036] The insole 4 is made of memory foam material and is cut into a suitable size according to the shape and size of the sole. The counterweight blocks 5 are made of lead blocks and are cut into multiple identical small strip shapes according to the shape of the insole. The width and length of each small strip are adapted to the insole, and the thickness is determined according to the required weight. In this embodiment, the weight of each small strip counterweight block is about 50 grams, and a total of 4 small strip counterweight blocks are set, with a total weight of about 200 grams.

[0037] Place multiple counterweight blocks 5 parallel to each other at the bottom of the insole 4, and use high-strength adhesive to tightly bond the counterweight blocks 5 to each other and to the bottom of the insole 4 to ensure that the positions of the counterweight blocks on the insole are fixed and evenly distributed; place the insole 4 with counterweight blocks inside the shoe upper 2 so that it fits tightly with the sole 1; connect the shoe upper 2 and the upper 3 through a stitching process, and install an adjustable strap 301 on the upper 3. The strap 301 is made of nylon material and is equipped with a plastic adjustment buckle, which is convenient for users to adjust according to the fatness or thinness of their feet.

[0038] When wearing the functional shoes of this embodiment for daily walking activities, walking about 5,000 - 8,000 steps per day and continuously wearing them for 3 months, it is found through professional muscle strength testing equipment that the strength of the quadriceps femoris around the knee joint can be increased by about 15% - 20% on average. For example, if the maximum contraction force of the quadriceps femoris was originally 300 Newtons, it can be increased to 345 - 360 Newtons after wearing; using a joint stability testing instrument, tests were conducted before wearing and 6 months after wearing respectively, and the results show that the displacement of the knee joint in the front-back direction is reduced by about 10% - 15%. If the average front-back displacement before wearing was 5 millimeters, it can be reduced to 4.25 - 4.5 millimeters after wearing; for some people with mild knee discomfort (such as occasional soreness and dull pain), tests were conducted, and after wearing the functional shoes for 2 weeks, about 60% of the subjects reported a reduction in pain frequency. Originally, pain might occur 3 - 4 times a week, and after wearing, it was reduced to 1 - 2 times; after wearing for 3 months, about 70% of the subjects had a reduction in pain intensity, and the pain score (using the visual analogue scale, 0 - 10 points) decreased from an average of 4 - 5 points to 2 - 3 points.

[0039] 2.2. Example 2:

[0040] The materials of the sole 1, the shoe upper 2 and the upper 3 are the same as those in Example 1.

[0041] The insole 4 is made of pure cotton and is first made into a complete insole shape, and then an opening 401 matching the shape of the counterweight 5 is opened at the center of the bottom of the insole. The counterweight 5 is a whole piece of lead, the shape of which is consistent with the shape of the insole 4, and the thickness is determined according to the design requirements. In this embodiment, the weight of the whole counterweight is about 300 grams.

[0042] The counterweight 5 is inserted into the bottom of the insole 4 through the opening 401 so that the counterweight fits tightly to the insole.

[0043] Put the insole 4 into the upper 2 and place it on the sole 1, then sew the upper 2 and the vamp 3 together, and install the binding strap 301 on the vamp 3.

[0044] Because of its heavy weight, the muscle stimulation is stronger when performing the same amount of daily activities (5000-8000 steps per day). After wearing it for 3 months, the quadriceps strength can be increased by an average of about 25%-30%. If the initial maximum contraction force of the quadriceps is 300 Newtons, it can be increased to 375-390 Newtons after wearing; in terms of joint stability, the angle change range of the knee joint in the direction of valgus and valgus is reduced by about 12%-18% after wearing it for 6 months. For example, the range of valgus and valgus angle change before wearing is 8 degrees, which can be reduced to 6.5-7 degrees after wearing; for people with knee discomfort, after wearing it for 2 weeks, about 70% of the subjects began to reduce the frequency of pain; after wearing it for 3 months, about 80% of the subjects had significantly reduced pain, and the pain score was reduced from an average of 4-5 points to 1-2 points. At the same time, in actions that put more pressure on the knee joints, such as going up and down stairs, the discomfort of the subjects has also been significantly improved. The knee pain score when going up and down stairs may reach 6-7 points, which can be reduced to 3-4 points after wearing it.

[0045] In actual use, the user first selects the appropriate embodiment product according to their own needs. When wearing for the first time, the strap 301 can be adjusted to a relatively loose state, and after putting on the shoes, the strap can be gradually tightened according to the comfort of the feet to ensure that the shoes fit closely to the feet. During walking or exercise, the user can obviously feel the weight of the feet increase, and the knee joint needs to pay more strength when moving. With the increase of use time, the muscles around the knee joint will gradually adapt to this load, and be exercised and strengthened. For patients with knee joint diseases or people in the rehabilitation period, it is recommended to adjust the wearing time and frequency according to their own rehabilitation progress under the guidance of a doctor or rehabilitation therapist to achieve the best rehabilitation effect. At the same time, regularly check the wear of the shoes, especially the connection between the sole and the counterweight block, if there is looseness or damage, it should be repaired or replaced in time.

[0046] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to the technical solution without creative efforts, they shall fall within the protection scope of the present invention.
