Abstract
Description
Technical Field
[0001] This invention relates to the field of socks, specifically to a sports sock with a functionally partitioned silicone layer. Background Technology
[0002] In existing technologies, sports socks typically employ a one-piece silicone coating or a full-sole anti-slip structure to enhance friction between the foot and the shoe. While such designs can prevent foot slippage to some extent, they generally suffer from problems such as rigid structure, poor breathability, and reduced flexibility. Because the silicone material is continuously distributed throughout the sock sole, the elasticity of the sock is limited in certain areas, affecting wearing comfort and natural gait. This is especially problematic in sports requiring precise foot control, such as golf swings, where it is difficult to balance dynamic stability and flexibility.
[0003] Furthermore, traditional designs fail to consider the differences in actual pressure distribution across different areas of the foot during exercise, as well as the varying pressure levels on each foot. This lack of targeted reinforcement at key pressure points results in inefficient distribution of cushioning and support. Some products attempt to improve localized performance through patterned silicone printing, but these methods remain limited to planar and homogeneous approaches, failing to achieve on-demand layout and functional zoning. This leads to unnecessary material accumulation in non-load-bearing areas and stress concentration in load-bearing areas. These structures not only increase ineffective weight but also weaken the original fit and breathability of the socks, failing to meet the comprehensive demands of high-end sports scenarios for precise control, long-lasting comfort, and efficient energy transfer.
[0004] Korean patent application with publication number "KR101102167B1" discloses a sports sock with functional zones. The sock uses different silicone layer structures for different foot areas. However, the functional zones are roughly divided, and the dynamic mechanical response between the zones is not considered. The silicone and the base are simply bonded together, making them easy to fall off. It also lacks a refined design for the coordination of the left and right feet in specific sports (such as golf). Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a sports sock with functionally zoned silicone layers. This solves the technical problems of existing sports socks, which, due to the lack of effective cushioning and moisture-wicking zoning design, lead to foot fatigue, localized friction damage, and poor comfort caused by uneven pressure application on both feet during prolonged use.
[0006] The present invention provides a sports sock with a functionally partitioned silicone layer. The sports sock includes a main sock and a secondary sock. Both the main sock and the secondary sock include a sock body and a sock cuff connected above the sock body. The sock body includes a sock frame and a silicone layer structure disposed at the bottom of the sock frame. The silicone layer structure includes the following regions: The forefoot thrust zone includes several strip-shaped silicone blocks, which are arranged at the ends of the first to fifth metatarsals along a direction perpendicular to the length of the metatarsals; The arch support area includes several silicone support strips, which are arranged longitudinally along the inner side of the arch. The heel stabilization zone includes several arc-shaped silicone segments, which are arranged in a C-shaped semi-ring or an O-shaped full ring structure around the heel. The toe root gripping area includes several silicone dots, which are arranged below the first to fifth metatarsophalangeal joints. The hardness of the strip silicone block in the forefoot thrust area of the main sock is higher than that of the strip silicone block in the forefoot thrust area of the auxiliary sock. The silicone support band in the arch support area of the sock gradually decreases in thickness from front to back; The arc-shaped silicone segment of the heel stabilization area of the main sock surrounds the inner and rear sides of the heel, and the arc-shaped silicone segment of the heel stabilization area of the secondary sock surrounds the center and outer side of the heel. The density of silicone dots in the toe grip area of the main sock, located below the fifth metatarsophalangeal joint, is less than the density of silicone dots in the toe grip area of the secondary sock, located below the fifth metatarsophalangeal joint.
[0007] Furthermore, the length of the strip silicone block is 8-15 mm, the width is 1.5-3 mm, the spacing between each two adjacent strip silicone blocks is 2-4 mm, and the edge of the strip silicone block is provided with a micro-arc chamfer with a radius of curvature of 0.2-0.5 mm.
[0008] Furthermore, the strip-shaped silicone block includes a base layer in contact with the sock body and a surface layer away from the sock body, wherein the Shore hardness of the base layer is less than that of the surface layer.
[0009] Furthermore, the length direction of the silicone support strip is parallel to the center line of the foot, its thickness is 0.6-1.0 mm, and the cross-section of the silicone support strip is "I" shaped or "T" shaped.
[0010] Furthermore, the surface of the silicone support strip is provided with uniformly distributed raised textures, the raised height of which is 0.1-0.2 mm.
[0011] Furthermore, the thickness of the arc-shaped silicone segment is 0.8-1.2 mm, the radius of curvature of its arc is 28-35 mm, and the interval between each two adjacent arc-shaped silicone segments is 0.5-1.0 mm. The side of the arc-shaped silicone segment is provided with fin-shaped protrusions and / or corrugated protrusions.
[0012] Furthermore, the silicone dot has a circular or elliptical structure with a maximum diameter of 2-5 mm and a height of 0.6-1.0 mm. The top of the silicone dot is provided with a spherical protrusion with a radius of curvature of 1.5-3 mm.
[0013] Furthermore, the silicone dots have a core-encapsulation structure, and the Shore hardness of the core silicone material of the silicone dots is lower than that of the encapsulation silicone material.
[0014] Furthermore, the front end of the strip-shaped silicone block closest to the center of the foot in the forefoot thrust zone and the silicone support band in the arch support zone are provided with silicone connecting ribs. The width of the silicone connecting ribs is 0.5~0.8 mm, and the Shore hardness of the silicone connecting ribs is less than that of the strip-shaped silicone block and the silicone support band.
[0015] Furthermore, the surface of the silicone layer structure is textured by plasma treatment, and the silicone material used in the silicone layer structure is doped with elastic particles.
[0016] Furthermore, the silicone layer structure is formed by injecting silicone through silicone injection channels reserved during the manufacturing process of the sock body using local yarn filling and embedding techniques.
[0017] Furthermore, the silicone material used in the silicone layer structure is doped with biomechanical sensors.
[0018] This invention provides a sports sock with a functionally partitioned silicone layer, comprising a sock body and a silicone layer structure disposed at the bottom of the sock body. The silicone layer structure consists of multiple independently arranged silicone regions, each corresponding to a dynamic pressure distribution area on the sole of the foot during a golf swing, and arranged based on the spatial location of key pressure points on the sole. Each silicone region is disposed in the weight-bearing area of the sole, and no silicone is disposed in the non-weight-bearing areas to maintain the original structural characteristics of the sock body in the non-weight-bearing areas. Each silicone region is fixed to a designated position on the inner or outer side of the sock by bonding or integral molding, forming discrete functional response units.
[0019] Furthermore, this invention designs different structures for the silicone layers in different areas. In the forefoot thrust zone, inner and outer silicone layers of varying hardness are used, while a highly elastic core-coating silicone structure is used in the toe grip area. Each functional unit achieves synergy between "buffering-anti-slip" or "adhesion-conduction." Specially shaped protrusions are added to the sides of the silicone segment in the heel stability zone, and the cross-section of the silicone support band in the arch support zone is specially shaped, upgrading the function from "passive presence" to "active response," directly optimizing for the dynamic and multi-directional mechanical loads during a golf swing.
[0020] Furthermore, the sports socks with functionally partitioned silicone layers of the present invention distinguish between primary and secondary socks for both feet, and adjust the structure and properties of the silicone in the same areas of the primary and secondary socks accordingly to adapt to different pressure points of different feet.
[0021] The sports socks of this invention enhance the anti-slip, cushioning, and support performance of key areas while retaining the original flexibility and breathability of the sock body. This avoids stiffness and discomfort caused by full-sole silicone coverage. Each silicone block is fixed to a designated position on the inner or outer side of the sock by bonding or integral molding, forming discrete functional response units. This not only improves the efficiency of local stress dispersion but also enhances the frictional stability between the sock body and the sole, effectively preventing the foot from sliding inside the shoe during exercise and improving motion transmission accuracy and athletic performance.

Detailed Implementation
[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. The principles and features of the present invention are described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The embodiments given are only for explaining the present invention and are not intended to limit the scope of the present invention.
[0026] This invention provides a sports sock with a functionally partitioned silicone layer. The sports sock includes a dominant sock and a secondary sock, which correspond to the dominant and non-dominant hand in golf. For example, for a right-handed player (whose dominant hand is right), the left side of the body needs to push off the ground forcefully during the downswing and follow-through to transfer power. Therefore, the left foot corresponding to the left side of the body is the dominant foot, and the sock corresponding to the dominant foot is called the dominant sock. The right foot is the secondary foot, and the sock corresponding to the secondary foot is called the secondary sock. Conversely, if the dominant hand is left-handed, the dominant and secondary socks also need to be adjusted accordingly. The following explanation uses a right-handed player with a dominant sock corresponding to the left foot as an example. In actual production, adjustments need to be made based on the specific left and right feet, and production volume needs to be adjusted according to market demand for players with the left or right foot as the dominant foot.
[0027] Reference Figure 1 As shown, both the main sock and the auxiliary sock of this sports sock include a sock body 1 and a sock leg 2 connected to the upper part of the sock body 1. The sock body 1 and the sock leg 2 are integrally molded. The sock body 1 includes a sock body and a silicone layer structure disposed at the bottom of the sock body. The sock body of the sports sock of this invention is a breathable mesh structure knitted from cotton, sweat-wicking yarn and / or polyester fiber, which has good elasticity, fit and breathability, and can closely fit the contour of the foot and naturally extend with the shape of the foot. The silicone layer structure of the sports sock of this invention will be described in detail below.
[0028] Specifically, the silicone layer structure of this invention includes the following areas: a forefoot thrust zone 11, an arch support zone 12, a heel stability zone 13, and a toe grip zone 14. Traditional sports socks often employ a full-coverage silicone layer design at the bottom, resulting in reduced flexibility and breathability, and failing to accurately respond to the dynamic pressure distribution of the foot during a golf swing. This invention, based on the specific areas of pressure on the foot during a golf swing, places the silicone layer in key pressure-bearing areas at the bottom of the sock. It allows for spatial layout according to the dynamic pressure distribution characteristics of the foot during a golf swing, precisely configuring the position of key pressure points for different feet. Furthermore, it provides support and anti-slip design for the differences in different functional areas, preventing the foot from sliding or rotating inside the shoe, thus affecting movement stability and athletic performance.
[0029] The forefoot thrust zone 11, arch support zone 12, heel stability zone 13, and toe root gripping zone 14 of this invention precisely correspond to key force points such as the metatarsal ball, the medial longitudinal arch path, the center and lateral side of the heel, and below the first to fifth metatarsophalangeal joints. They can be spatially positioned based on the dynamic pressure distribution characteristics of the sole, and their distribution pattern is optimized and determined based on pressure test data from three-dimensional sole scanning and golf swing. Each silicone block, as an independent functional response unit, can provide directional friction, local support, or cushioning upon contact with the insole, thereby improving stability and force transmission efficiency during movement.
[0030] In addition, the area outside the silicone layer retains the elasticity and breathability of the original knitted structure of the sock. This discontinuous distribution design avoids the stiffness and heat buildup caused by large-area silicone covering, while ensuring a harmonious balance between functionality and comfort.
[0031] The location and structure of each functional area will be described in detail below.
[0032] Specifically, the forefoot thrust zone 11 includes several strip-shaped silicone blocks 111, which are arranged at the ends of the first to fifth metatarsal bones along a direction perpendicular to the length of the metatarsal bones, such as... Figure 2As shown, the ends of the first to fifth metatarsals refer to the ends where the metatarsals connect to the phalanges, but do not cover the joints. Specifically, in some embodiments, the forefoot thrust zone 11 includes several strip-shaped silicone blocks 111. Each strip-shaped silicone block 111 is rectangular, with a length of 8-15 mm and a width of 1.5-3 mm. These strip-shaped silicone blocks 111 are arranged perpendicular to the length direction of the first to fifth metatarsals, that is, the strip-shaped silicone blocks 111 are arranged across the forefoot, and are parallel to each other. The spacing between each two adjacent strip-shaped silicone blocks 111 is 2-4 mm. Thus, the several strip-shaped silicone blocks 111 together form a directional friction array, which can enhance the lateral grip performance during push-off to effectively resist the forefoot sliding back and forth within the shoe cavity during the swing power phase.
[0033] The forefoot thrust zone of this invention features a strip-shaped silicone block with a micro-arc chamfered edge. The radius of curvature of this chamfer is 0.2-0.5 mm, which effectively reduces scratch damage to the insole surface fabric and extends the service life of the socks and shoes. This strip-shaped silicone block 111 is made of high-hardness liquid silicone material to provide a rigid contact interface and improve force transmission efficiency.
[0034] Furthermore, the strip-shaped silicone block adopts a gradient hardness structure. Specifically, the strip-shaped silicone block includes a base layer in contact with the sock body and a surface layer away from the sock body. The Shore hardness of the base layer is lower than that of the surface layer. In some embodiments, the Shore hardness of the base layer in contact with the sock body can be, for example, 50-55 Shore A. The slightly higher elasticity can increase the adhesion between the silicone layer and the sock body and cushion the impact on the foot. The ablation hardness of the surface layer away from the sock body can be, for example, 65-70 Shore A. The higher Shore hardness of the surface layer provides a rigid thrust interface.
[0035] Furthermore, the hardness of the silicone strip in the forefoot thrust zone of the main sock is higher than that of the silicone strip in the forefoot thrust zone of the secondary sock. Here, hardness refers to the fact that both the base layer and the surface layer of the main sock are harder than those of the secondary sock. For example, the Shore A hardness of the base layer of the silicone strip in the main sock is 55 Shore A, and the Shore A hardness of the surface layer is 70 Shore A, while the Shore A hardness of the base layer of the silicone strip in the secondary sock is 50 Shore A, and the Shore A hardness of the surface layer is 65 Shore A. A golf swing is a full-body rotational power generation process. For right-handed players (whose dominant hand is right), the left side of the body (left foot, usually the main foot) needs to push off the ground forcefully during the downswing and follow-through to transfer power (i.e., "thrust"). The high-hardness silicone strip provides a stable "power platform" for the left forefoot, preventing slippage on wet grass and ensuring efficient power transmission. The secondary foot (right foot) plays a more supporting and rotational pivot role in this process; a slightly lower hardness design increases comfort and ground feel.
[0036] Below the forefoot thrust zone 11, an arch support zone 12 is provided in the arch area. This arch support zone 12 includes several silicone support strips 121. The length direction of each silicone support strip 121 is parallel to the midline of the sole, and its thickness is 0.6-1.0 mm. The silicone support strips 121 are arranged longitudinally along the inner side of the arch, such as... Figure 2 As shown, the silicone support band 121 extends from the rear edge of the forefoot ball to the front edge of the heel, covering the main load-bearing path of the medial longitudinal arch. The silicone support band 121 has moderate elasticity, allowing for natural arch rise and fall while providing lightweight support. Furthermore, the silicone support band 121 is fixed to the inside of the sock and can be arranged in a continuous band or segmented layout, depending on design requirements, to balance support rigidity and lateral flexibility.
[0037] Furthermore, in some embodiments, the surface of the silicone support strip 121 is provided with uniformly distributed raised textures (not shown in the figure). The height of the raised textures is 0.1-0.2 mm, and they are uniformly distributed on the upper surface of the silicone support strip 121. This enhances the microscopic engagement between the sock and the insole, preventing micro-slippage in the arch area during rotational movements, thereby improving overall stability. This textured structure is constructed simultaneously during the molding process, requiring no additional processing steps, ensuring production efficiency and consistency. The cross-section of the silicone support strip 121 is "I"-shaped or "T"-shaped, rather than a simple rectangular strip. This structure provides stronger support under vertical pressure and is more elastic under lateral torsion, better meeting the mechanical requirements of the arch during rotational movements.
[0038] Furthermore, the silicone support band 121 of the arch support area 12 of the secondary foot sock gradually decreases in thickness from front to back. In other words, the silicone support band 121 of the arch support area 12 has a gradual design in the longitudinal direction, with the thickness at the front being greater than that at the back. This is beneficial for providing better support to the front of the arch after applying force. The swing involves a significant transfer of the center of gravity (from the secondary foot to the primary foot). The secondary foot bears the center of gravity during the backswing and needs good arch support to maintain body balance. The design of the arch support band of the secondary foot sock, which "gradually decreases in thickness from front to back," can adapt to the dynamic deformation of the arch during the swing, providing support without hindering the natural torsion of the foot.
[0039] At the very back of the sock, corresponding to the heel, a heel stabilization zone 13 is arranged around the center and outer high-pressure area of the heel. This heel stabilization zone 13 includes several arc-shaped silicone segments 131, which are arranged in a C-shaped semi-ring or O-shaped full-ring structure around the heel to suppress lateral displacement and excessive rotation of the heel during the swing rotation, thereby improving dynamic stability.
[0040] The curved silicone segment 131 may include, for example, 6-10 segments, each with a thickness of 0.8-1.2 mm. The curvature of each curved silicone segment matches the anatomical contour of the heel, with a radius of curvature of 28-35 mm, ensuring a close fit to the heel shape and achieving uniform pressure distribution. The spacing between any two adjacent curved silicone segments 131 is 0.5-1.0 mm, allowing for localized compression and deformation to accommodate the dynamic changes in the heel during different swing phases, while maintaining the anchoring effect of the overall ring structure.
[0041] The sides of the curved silicone segment 131 are provided with fin-like protrusions and / or corrugated protrusions. When there is no lateral sliding of the heel, the protrusions provide basic friction; when a lateral force is detected, the protrusions bend in a specific direction, increasing the contact area and resistance, and providing "active" stability.
[0042] Furthermore, the curved silicone segment 131 of the heel stabilization zone 13 of the main sock surrounds the inner and rear sides of the heel, while the curved silicone segment 131 of the heel stabilization zone 13 of the secondary sock surrounds the center and outer sides of the heel. These different surrounding positions are because the main and secondary socks correspond to different force application points on the heel at different stages of the golf swing, thus providing different mechanical support to the heel. A golf stance requires stable feet. The main sock's emphasis on the inner and rear sides prevents the left heel from flipping outwards due to the strong torque during the swing; the secondary sock's emphasis on the center and outer sides prevents the right foot from sliding inwards during the backswing. This asymmetrical design greatly enhances torque resistance stability.
[0043] The above silicone layer structure corresponds to the entire sole of the foot. It should be noted that there are several of the above-mentioned strip silicone blocks 111, silicone support strips 121 and arc-shaped silicone segments 131. These "several" usually refer to two or more. Unless otherwise specified, the specific number can be adjusted according to the size of the sock. For example, if the sock size is large, more silicone layer structures can be set, and vice versa. This ensures that the corresponding functions can be fully realized in the corresponding areas.
[0044] Furthermore, during a golf swing, corresponding forces are also applied to the toes. Therefore, the silicone layer structure of the present invention also includes a toe root gripping area 14 located below the first to fifth metatarsophalangeal joints to enhance the initial grip force of the foot during the initial stage of the swing. Figure 2 As shown, the toe root gripping area 14 includes several silicone dots 141 arranged below the first to fifth metatarsophalangeal joints. Each silicone dot 141 is a round or elliptical structure with a maximum diameter of 2-5 mm and a height of 0.6-1.0 mm. Further, in some embodiments, the top of each silicone dot 141 has a spherical protrusion (not shown in the figure) with a radius of curvature of 1.5-3 mm, which can concentrate pressure upon contact with the ground, rapidly stimulating a frictional response. These silicone dots 141 are arranged asymmetrically and are preferentially concentrated below the first and fifth metatarsal heads to match the biomechanical characteristics of the human body, which exerts greater force on both sides during initiation movements.
[0045] Furthermore, all silicone dots 141 of the present invention adopt a core-coating structure. The Shore A hardness of the core silicone material of the silicone dot is lower than that of the coating silicone material. For example, the Shore A hardness of the core silicone material can be 30-40 Shore A, and the Shore A hardness of the coating silicone material can be 55-65 Shore A. Based on the combination of silicone dots and strip silicone blocks, the functional unit can achieve synergy of "buffering-anti-slip" or "adhesion-conduction".
[0046] Furthermore, the specific structures of the toe-base gripping areas of the main sock and the secondary sock of this invention are also different. The distribution density of silicone dots in the toe-base gripping area of the main sock, located below the fifth metatarsophalangeal joint, is less than that of the secondary sock. The fifth metatarsophalangeal joint (little toe side) is an important balance point in a golf swing. The secondary foot requires extremely strong grip as a fulcrum during the backswing; therefore, increasing the density of silicone dots below the fifth metatarsophalangeal joint effectively prevents toes from moving inside the sock, improving slip resistance and balance control.
[0047] Furthermore, in some embodiments of the present invention, the silicone structures in each region are not completely discrete. For example, the front end of the strip-shaped silicone block closest to the center of the foot in the forefoot thrust zone and the silicone support band in the arch support zone are provided with silicone connecting ribs 15. Figure 2 As shown, Figure 2 To clearly illustrate the silicone connecting rib 15, it is shown in the undersock but not in the main sock. The silicone connecting rib 15 has a width of 0.5~0.8 mm, and its Shore hardness is less than that of the silicone strip and the silicone support band. For example, the Shore hardness of the silicone connecting rib 15 can be 20-25 Shore A. One or two silicone connecting ribs can be provided. Silicone connecting ribs 15 are provided at the front ends of the silicone strip closest to the center of the foot in the forefoot thrust zone and the silicone support band in the arch support zone. This thin rib does not provide primary support or anti-slip; its function is to coordinate stress transfer between the two main functional zones when the foot undergoes minute deformation, preventing the silicone edge from cutting into the sock fabric and improving overall durability. Therefore, the sports sock of this invention emphasizes the synergy of each zone as a system, rather than simply a collection of areas. This meticulous "separate yet cohesive" design considers long-term reliability.
[0048] Furthermore, the surface of the silicone layer structure is textured through plasma treatment, and the silicone material used in the silicone layer structure is doped with elastic particles. The surface of the silicone layer structure of the sports sock of the present invention (at least the silicone layer surface of the forefoot thrust area and the toe grip area) is formed with micro-nano-level rough texture through plasma treatment. This allows the dynamic friction coefficient of the silicone layer structure to be 10%-25% higher than the static friction coefficient, which can be used to prevent "sudden slippage" during exercise, making it ideal for the instantaneous transition from static preparation to dynamic acceleration in a golf swing. The aforementioned elastic particles can be, for example, elastic microspheres with a diameter of 10-100 nm. These elastic microspheres can also have a hollow structure, which can provide additional cushioning under pressure. Furthermore, if hollow microspheres are used, they can absorb heat when the rubber fabric temperature rises, reducing the feeling of heat buildup in the silicone area. Thus, the sports sock of the present invention delves into the material engineering level from macroscopic structural design, solving the potential defects of existing anti-slip socks in terms of dynamic friction and local thermal comfort.
[0049] Furthermore, in some embodiments, the silicone layer structure of the sports socks of the present invention is not distributed on the bottom of the sock body using traditional bonding and / or screen printing methods. Instead, silicone injection channels are pre-reserved on the sock body during manufacturing through local yarn filling and embedding techniques. Therefore, the silicone layer structure of the present invention is formed by injection through the silicone injection channels pre-reserved during the sock body manufacturing process. This allows the silicone material to not only adhere to the fabric surface after curing, but also partially penetrate and encapsulate adjacent fabric fibers, forming a mechanically interlocking structure. This significantly improves the bonding strength between the silicone layer and the sock body, solving the problem of peeling that may occur after long-term washing and use. Simultaneously, this process enables more precise silicone positioning and thickness control.
[0050] Furthermore, the composite structure of the present invention, namely the formation of the base layer and surface layer of the strip-shaped silicone block in the forefoot thrust zone and the core-encapsulation structure of the silicone dots in the toe root gripping area, are all formed using a multi-channel injection system. This multi-channel injection system enables gradient control of material hardness in different areas, further optimizing the performance of the zoned functional areas. This design achieves closed-loop matching from pressure recognition to functional response, significantly improving the support, anti-slip properties, and wearing comfort of sports socks during complex movements.
[0051] Furthermore, to better record the foot mechanics of golfers, the silicone material used in the silicone layer structure of the silicone socks of this invention is doped with a biomechanical sensor. This biomechanical sensor, typically a micrometer-scale mechanical sensor, can be injected into the silicone material using the aforementioned multi-channel injection system to collect pressure data.
[0052] Of course, based on this, more intelligent elements can be integrated into the silicone layer structure of the present invention. For example, a substrate that can be hot-pressed to composite conductive fabric can be doped into the silicone material, providing the possibility for subsequent integration of foot heating or muscle electrical stimulation functions.
[0053] Each of the aforementioned silicone layer structures is positioned in the weight-bearing area of the sole, forming discrete functional response units. Each unit functions independently without affecting the others. These silicone blocks are differentiated in shape, thickness, and hardness according to the biomechanical requirements of their respective areas, thereby achieving targeted support for different stages of movement. Furthermore, no silicone layer structures are placed in non-weight-bearing areas to maintain the original structural characteristics of the sock in these areas. This design is based on measured data of dynamic pressure distribution on the sole during a golf swing, precisely placing the silicone functional units in high-pressure contact areas, including the forefoot thrust zone 11, heel stabilization ring, arch support strip, and toe grip area 14. The original knitted structure of the sock is completely preserved in the midfoot transition zone, the instep extension zone, and the low-stress edge zones.
[0054] Therefore, the silicone layer structure in each of the aforementioned areas is discretized based on the spatial distribution of key pressure points on the sole of the foot, existing only in high-pressure areas. Silicone layers are not placed in non-weight-bearing areas such as the arch transition zone and the instep extension zone, thus preserving the elasticity and breathability of the original knitted structure of the sock. Furthermore, this structural design is based on biomechanical analysis of the differentiated force patterns of the primary and secondary feet during different stages of a golf swing (backswing, downswing, release, and follow-through), aiming to provide optimal support for each foot in its specific role, rather than simply providing "one-point anti-slip." Further, the strip-shaped silicone blocks and silicone dots of this invention utilize composite silicone units, achieving a unity of cushioning and rigidity transmission. In laboratory simulation tests, compared to single-hardness silicone, energy return efficiency is increased by 15%, while peak pressure is reduced by 10%.
[0055] Because the non-load-bearing areas are not covered with any silicone material, this part of the sock maintains its original elasticity, breathability, and soft feel, avoiding the overall stiffness and heat and moisture buildup problems caused by full-soled rubber. Especially in the outer arch, the instep connection area, and the sock cuff, a mesh structure woven from moisture-wicking yarn is used to ensure that the local microclimate regulation ability is not affected, improving comfort during extended wear. Therefore, the sports sock of this invention achieves an integrated design of anti-slip, support, cushioning, and comfort. This structure is particularly suitable for the needs of complex weight transfer and rotational movements in golf, effectively improving the athlete's movement stability and performance consistency. Furthermore, this selective layout avoids the stiffness caused by redundant materials while ensuring a balance between functional enhancement and wearing comfort.
[0056] Meanwhile, this layout ensures that the silicone layer appears only in key locations where enhanced friction and support are needed, creating a lightweight functional structure that is "reinforced on demand." For example, although there is an arch support strip along the medial longitudinal arch of the foot, it is a thin, discrete strip structure that does not extend into the surrounding non-weight-bearing areas, thus allowing the midfoot area to bend and twist naturally during movement without affecting the smoothness of foot physiological movements.
[0057] The silicone-free design in non-load-bearing areas also helps reduce overall weight and material usage, improving production economy and environmental friendliness. By precisely defining the boundaries between load-bearing and non-load-bearing areas, an optimal balance between functionality and structure is achieved. This ensures foot stability during key phases of the swing while preserving the original flexibility and fit of the sock to the greatest extent, meeting the dual needs of golf for precise control and comfort.
[0058] Each silicone block is fixed to a designated position on the inside or outside of the sock by adhesive bonding or integral molding, forming discrete functional response units. This fixing method ensures that each silicone block is stably attached to the sock during exercise and will not fall off or shift due to repeated bending, twisting of the foot or friction with the insole, while maintaining its independent distribution state, achieving a precise mechanical response in a "functional island" manner.
[0059] The molding of all silicone layers in this invention is optimized around the integrated goal of functionality and comfort. Outside the silicone distribution area, especially in non-load-bearing and high-deformation areas, a breathable mesh structure woven from moisture-wicking yarns is retained to avoid affecting the overall thermal and moisture management performance due to localized material addition. Through the above-mentioned bonding or integral molding methods, each silicone block is not only firmly fixed in the designated position, but also works collaboratively as an independent unit to form an intelligent sock sole system that has both zoned reinforcement function and freedom of wearing, fully adapting to the dynamic mechanical requirements during a golf swing.
[0060] As described above, the sports socks of the present invention are suitable for a variety of sports scenarios and have a wide range of applications. They can be adapted to a variety of athletes. Furthermore, the several components mentioned in the present invention can be adjusted according to the specific size (size) of the socks. For example, the number of several strip silicone blocks can be increased when the size of the socks is large, and decreased accordingly when the size is small. The same applies to other silicone layer structures.
[0061] Furthermore, in other embodiments of the present invention, the sports socks of the present invention can also be applied to other sports that require unilateral force application, center transfer, or rotation. For example, the sports socks of the present invention can also be applied to the following sports: Tennis / Badminton involves a lot of sudden stops, changes of direction, and single-leg jumps to hit the ball. For example, the dominant foot needs to push off the ground powerfully when jumping and smashing or volleying. The high-hardness forefoot thrust zone can provide explosive power. The secondary foot is responsible for sudden stops and braking, requiring stronger anti-slip properties (high density of the toe root grip area) and lateral support (the heel stability zone is located on the outer side). In baseball / softball, pitching and hitting involve a clear division of labor between the pitcher's "pivot foot" (support foot / secondary foot) and "power foot" (primary foot). The batter's power generation pattern is similar to that of a golfer. For example, pitching requires an extremely stable center of rotation, and the arch support and heel stability design of the secondary foot sock can prevent the secondary foot from slipping. When pushing off the ground during pitching or rotating the body during hitting, high rigidity support is required in the forefoot. In track and field (such as sprinting, long jump, and high jump), the starting foot can be used as the primary foot, requiring a high forefoot hardness to counteract the reaction force from the starting blocks or the ground. The secondary foot, as the auxiliary foot, swings in the air or maintains balance, requiring a lighter and more fitted support.
