Description

Technical Field

[0001] This utility model relates to the field of footwear technology, and in particular to a proprioceptive sole and shoe. Background Technology

[0002] Modern running shoes have thick midsoles in pursuit of good shock absorption, which weakens the ground feedback mechanism and significantly reduces the dynamic response of the foot's proprioceptive system. This excessive cushioning design can lead to insufficient ankle stability on uneven surfaces. At the same time, wearing sports shoes made of highly flexible materials for a long time can easily lead to a decline in foot muscle function due to a lack of mechanical stimulation to the plantar fascia and small muscle groups.

[0003] Existing proprioceptive shoes embed support structures within the sole, allowing the user's foot to receive road surface information through feedback from these support pillars, thereby enhancing proprioceptive awareness of the road surface. However, the support structures in existing proprioceptive shoes are typically cylindrical, resulting in poor tactile feedback from the road surface. Summary of the Invention

[0004] The purpose of this invention is to provide a proprioceptive sole and shoe to solve the problem of poor tactile feedback in existing proprioceptive shoes.

[0005] To achieve the above objectives, this utility model discloses a proprioceptive sole, comprising: a midsole and a sensing post, wherein the sensing post is embedded in the midsole, and the sensing post is at least located at the position of the midsole corresponding to the forefoot and heel, wherein the hardness of the sensing post is greater than that of the midsole, and the sensing post includes a head, wherein the upper edge of the longitudinal section of the head is an upwardly arched arc shape.

[0006] Preferably, the midsole has sensing posts on both sides of the heel.

[0007] Preferably, the insole is provided with the sensing posts corresponding to the positions of the second, third, fourth, and fifth toes.

[0008] Preferably, the sensing post is provided on the midsole at the position corresponding to the first metatarsal bone, the first phalanx, the fifth metatarsal bone, and the fifth phalanx.

[0009] Preferably, the sensing column is located at the bottom center.

[0010] Preferably, the Shore A hardness of the sensing post located at the heel position of the midsole is 5-10 HA higher than that of the midsole material.

[0011] Preferably, the Shore A hardness of the sensing post located in the midsole corresponding to the forefoot position is 3-5 HA higher than that of the midsole material.

[0012] Preferably, the sensing column includes a head and a rod, the head being disposed at the top of the rod, and the horizontal cross-sectional shape of the rod being circular, rectangular, triangular, or regular polygonal.

[0013] Preferably, the length of the rod of the sensor post located at the heel position in the midsole is 18-22mm, the length of the rod of the sensor post located at the metatarsal position in the midsole is 13-17mm, and the length of the rod of the sensor post located at the toe position in the midsole is 3-7mm.

[0014] Preferably, a shoe includes the aforementioned proprioceptive sole.

[0015] This utility model has the following beneficial effects:

[0016] 1. The sensor column design of this utility model aims to solve the problem of excessively thick soles in modern running shoes, which makes it difficult for the foot to perceive road surface information. By directly transmitting road surface signals to the sole of the foot, it enhances proprioception, thereby activating foot muscles and effectively preventing sports injuries.

[0017] 2. The position layout of the sensing columns in this utility model is based on the foot pressure distribution data, cleverly avoiding high-pressure areas, and evenly distributed on the inner and outer sides of the foot to accurately sense the inversion and supination of the foot, providing rich information for the muscle and nerve control system.

[0018] 3. The sensor column of this utility model is set to avoid the high pressure area on the sole of the foot, ensuring that the cushioning performance and wearing comfort of the midsole material are not affected, while realizing the effective transmission of road surface information.

[0019] 4. The hardness of the sensing column in this invention is regionalized according to the different sensitivity of different areas of the sole to stimulation. The threshold of the heel area is higher, while the threshold of the toe area is slightly lower but the sensing range is wider. This design can respond more accurately to pressure changes in different areas. Attached Figure Description

[0027] 100. Midsole; 110. Sensing post; 111. Head; 112. Shaft. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] like Figures 1-3 This invention provides a proprioceptive sole, comprising: a midsole 100 and sensing posts 110. The sensing posts 110 are embedded within the midsole 100, and are positioned at least at the forefoot and heel positions of the midsole 100. The hardness of the sensing posts 110 is greater than that of the midsole 100. The sensing posts 110 include a head 111, the upper edge of which has an upwardly arched arc shape in its longitudinal section. The sensing posts 110 cover most of the sole, from the forefoot to the heel, forming a three-dimensional sensing network that comprehensively enhances the foot's adaptability to the environment. The upwardly convex arc shape of the head 111 improves the comfort of stepping, and the rebound force provided by the sensing posts 110 during walking or exercise enhances the tactile feedback of the sole.

[0030] In this embodiment, the midsole 100 is provided with two sensing posts 110 on each side of the heel. The sensing posts 110 distributed on both sides help maintain foot balance and can also more sensitively detect changes in ground reaction force.

[0031] The midsole 100 has sensor posts 110 positioned at the locations of the second, third, fourth, and fifth toes. These sensor posts 110 under the toes enhance the toes' sensitivity to ground texture and slope, improving directional control during movement. Simultaneously, they assist the toes in naturally gripping the ground, improving the continuity of force application during propulsion and reducing compensatory injuries caused by weak toes.

[0032] The midsole 100 is equipped with sensor posts 110 corresponding to the positions of the first metatarsal, first phalanx, fifth metatarsal, and fifth phalanx. By sensing the pressure distribution in the metatarsal areas, it guides the foot to land in a more natural manner (such as forefoot / full-foot landing), reducing the burden on the knees and lower back. When weight is transferred to the metatarsals, the sensor posts 110 can also provide instant feedback to help adjust the center of gravity and avoid excessive pronation or supination.

[0033] The sensor post 110 is embedded in the midsole. The midsole 100 is the core area for cushioning and support. Embedding the sensor post 110 here allows for direct capture of ground reaction forces, enhancing the foot's immediate response to changes in the ground. In this embodiment, the sensor post 110 can be embedded using the following methods: 1. Co-injection molding: Using two injection molding machines, one for injecting the midsole and the other for injecting the sensor post 110. After the midsole injection is completed, the sensor post 110 material is injected into the predetermined position, allowing the two to bond together. 2. Intercalation injection molding: First, the sensor post 110 is pre-formed, and then embedded into the midsole material during the injection molding process.

[0034] The sensor post 110, located at the heel of the midsole (100), has a Shore A hardness 5-10 HA higher than the midsole material. Since the heel bears the entire body weight, the higher-hardness sensor post 110 reduces compression upon landing, providing clearer ground contact feedback and helping the user precisely control their center of gravity. The sensor post 110, located at the forefoot of the midsole (100), has a Shore A hardness 3-5 HA higher than the midsole material. The forefoot needs to balance flexibility and support; moderately increasing hardness provides sufficiently clear ground feedback.

[0035] The sensor post 110 includes a head 111 and a rod 112. The head 111 is located at the top of the rod 112. The rod 112 mainly serves to support or connect the head 111. The horizontal cross-sectional shape of the rod 112 can be irregular, such as trapezoidal or rhomboid, or it can be circular, rectangular, triangular, or regular polygonal, thus improving stability. The rod 112 of the sensor post 110 located at the heel position in the midsole 100 has a length of 18-22mm, the rod 112 of the sensor post 110 located at the metatarsal position in the midsole 100 has a length of 13-17mm, and the rod 112 of the sensor post 110 located at the toe position in the midsole 100 has a length of 3-7mm.

[0036] like Figure 4 As shown, in this embodiment, the sensing post 110 is mushroom-shaped, and the extended head 111 increases the contact area with the sole of the foot, converting local pressure into uniform pressure, which can reduce soreness during prolonged standing or exercise. Simultaneously, the raised head 111 forms a micro-convex structure, simulating the massage effect of pebbles, stimulating nerve endings in the sole of the foot, and enhancing proprioceptive feedback. The stepped design of the head 111 and the rod 112 effectively anchors the sensing post 110 in the midsole material, preventing displacement or detachment due to repeated pressure. Figure 5 , 6 As shown, in other embodiments, the sensing post 110 may also be configured in other shapes.

[0037] This utility model also discloses a shoe, including the aforementioned proprioceptive sole. Shoes with proprioceptive soles allow for clear perception of the ground conditions when worn, enhancing the body's tactile feedback to the ground.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
