Description

Technology Field

[0001] The present invention relates to an insole for golf shoes, and more specifically, to an insole for golf shoes that is inserted into the interior of a golf shoe to support the sole of the wearer's foot. Background Technology

[0003] Generally, insoles are inserted into the upper part of the shoe to directly support the wearer's soles, providing comfort while absorbing some of the impact during walking.

[0004] Recently, due to the increase in the number of people engaging in leisure activities, insoles developed to suit specific characteristics are being proposed in the leisure sector, such as hiking insoles.

[0005] In particular, golf requires the correct posture compared to other sports.

[0006] Figure 1 is a diagram showing the plantar pressure distribution that occurs during a golf swing, according to the swing posture stages.

[0007] As shown in Fig. 1, it can be seen that the contact area between the foot and the ground and the intensity of the force applied to the sole of the foot change during the swing motion.

[0008] In this swing posture, the left foot becomes the central axis of the swing during the impact motion, and the direction of the strike changes depending on the movement of the foot and upper body, and the direction of the ball's trajectory and distance are determined.

[0009] Generally, during the weight transfer process in a swing, both feet tend to tilt outward. As a result, it is difficult to maintain a consistent swing trajectory, the upper body twisting motion becomes less smooth, the lower body's bracing power decreases, and the range of lateral movement of the upper body during the swing increases, leading to reduced accuracy and power in striking, which in turn results in shorter distance and poorer direction.

[0038] Specific embodiments of the present invention will be described below with reference to the attached drawings.

[0039] FIGS. 2 and FIGS. 3 are a perspective view and a plan view schematically illustrating an insole for a golf shoe according to an embodiment of the present invention, and FIG. 4 is an enlarged view schematically illustrating area A in FIG. 3. FIG. 5 is a front view schematically illustrating the insole for a golf shoe, and FIG. 6 is a cross-sectional view schematically illustrating area B in FIG. 5.

[0040] And, FIG. 7 is a graph showing a comparison of body twisting at impact while wearing the above golf shoe insole and a conventional insole, FIG. 8 is a graph showing a comparison of upper body shaking during a swing, FIG. 9 is a graph showing a comparison of toe movement after impact, and FIG. 10 is a graph showing a comparison of the golf ball's carry, distance, and direction angle after impact.

[0041] Referring to FIGS. 2 to 10, an insole (100) for a golf shoe according to an embodiment of the present invention comprises a main body portion (200) on which the sole of the foot rests, a first cushion portion (310) provided on the main body portion (200) and supporting a part of the forefoot portion of the foot, and a second cushion portion (320) provided on the main body portion and supporting the remaining part of the forefoot portion, formed in a part of the portion on which the little toe rests and supporting the side of the forefoot portion.

[0042] That is, the first cushion part (310) and the second cushion part (320) are provided together on the front bottom surface of the main body part (200) to support the forefoot of the wearer's foot, and the second cushion part (320) is arranged to support the side of the forefoot where the little toe rests.

[0043] Through this, the outer side of the foot, which is the central axis of the swing during the weight transfer process in the swing motion, is supported by the second cushion part (320), thereby dispersing the force to the inside of the sole of the foot and supporting the foot so that it does not bend outward.

[0044] More specifically, referring to FIG. 3, the second cushion portion (320) may be formed such that the width (L2) parallel to the width direction of the sole of the foot is 10 to 40 percent of the width (L1) of the main body portion (200) on the same line (RL). At this time, the second cushion portion (320) may be formed such that its area decreases from the front to the rear along the length direction of the sole of the foot. That is, the second cushion portion (320) is formed in the area that supports the side of the foot where force is concentrated during a swing.

[0045] Additionally, referring to FIG. 6, the second cushion portion (320) may be formed with a thickness that protrudes 1 to 5 mm more than the first cushion portion (310). That is, the difference (△t) between the surface of the second cushion portion (320) and the surface of the first cushion portion (310) may be 1 to 5 mm.

[0046] Accordingly, the second cushion portion (320) may be formed to be thicker than 1 to 5 mm than the thickness of the first cushion portion (310).

[0047] For example, with reference to FIG. 6, the main body (200) may be formed such that the area (232) where the second cushion part (320) is provided is formed to be recessed inwardly compared to the area (231) where the first cushion part (310) is provided.

[0048] Through this, the thickness of the second cushion part (320) can be formed thicker, while the thickness (△t) protruding from the first cushion part (310) can be maintained at 1 to 5 mm, thereby further improving the support rigidity.

[0049] With this configuration, the load is concentrated on the second cushion part (320) during a swing, and since a greater force acts on the second cushion part (320) compared to the first cushion part (310), the second cushion part (320) is formed thicker to provide more stable support.

[0050] Furthermore, the second cushion part (320) may be formed from a material to have greater rigidity than the first cushion part (310).

[0051] For example, the second cushion part (320) may be formed from a gel material comprising at least one of TPE (Thermo Plastic Elastomer), urethane, and EVA (Ethylene-vinyl acetate copolymer).

[0052] At this time, the first cushion part (310) may be formed from a gel material comprising at least one of viscoelastic SEBS (Styrene Ethylene Butylene Styrene), urethane, and silicone.

[0053] Of course, the second cushion part (320) and the first cushion part (310) may be formed of the same material.

[0054] The foam materials used in conventional insoles have the problem of undergoing permanent deformation and losing elasticity with long-term use. Additionally, the shock absorption and durability of foam insoles may deteriorate with prolonged use.

[0055] Accordingly, in the present invention, the first cushion portion (310) and the second cushion portion (320) are formed using a viscoelastic gel material, so that even with long-term use, there is less deformation compared to existing materials, and shock absorption and elasticity can be maintained. Through this, excellent comfort can be provided to the user even during long-term walking, and foot fatigue can be reduced.

[0056] Also, referring to FIG. 4, the first cushion part (310) and a plurality of first hexagonal columns (311) may be formed in a honeycomb structure that shares a first partition (312), and the second cushion part (320) may also be formed in a honeycomb structure that shares a second hexagonal column (321) with a second partition (322).

[0057] Here, in order to increase the rigidity of the second cushion part (320) against compressive force compared to the first cushion part (310), the thickness of the second partition (322) may be formed to be thicker than the thickness of the first partition (312).

[0058] Here, the honeycomb structure may be a structure in which hexagons are arranged adjacently when viewed in cross-section horizontally with respect to the ground. Through such a honeycomb structure, the load can be optimally distributed to provide a comfortable fit even during long periods of walking. Of course, the cross-sectional shape of the honeycomb structure is not limited to hexagons, and it may have a cross-sectional shape in which polygons other than hexagons are arranged adjacently.

[0059] Furthermore, referring to FIG. 6, the main body (200) may comprise a surface layer (210) on which a foot rests, an intermediate layer (220) formed on the surface layer (210) and providing cushioning force, and a bottom layer (230) formed on the intermediate layer (220) and equipped with the first cushion part (310) and the second cushion part (320).

[0060] Here, the intermediate layer (220) may be made of Ortholite, and the bottom layer (230) may be made of EVA (Ethylene-vinyl acetate copolymer). Of course, the materials forming the intermediate layer (220) and the bottom layer (230) are not limited to these and may be made of various known materials.

[0061] Additionally, the bottom layer (230) may be formed such that the area (232) where the second cushion part (320) is provided is recessed inwardly compared to the area (231) where the first cushion part (310) is provided.

[0062] Furthermore, referring to FIG. 3, the device may further include a third cushion part (330) that is provided in the main body part (200) and supports the rear foot of the foot.

[0063] That is, the third cushion part (330) is configured to support the heel, which is the rear part of the foot. This third cushion part (330) may be made of the same material and shape as the first cushion part (310) or the second cushion part (320).

[0064] And, the main body (200) may further include an arch support (240) formed to protrude between the first cushion part (310) and the third cushion part (330) to support the arch of the foot.

[0065] The arch support member (240) can be formed at the highest point of the main body (200) so as to effectively contact the sole of the foot according to the shape of the foot. That is, the arch support member (240) makes close contact with the arch of the foot that is recessed inward from the sole, thereby stably supporting the entire sole of the foot. In addition, it can provide appropriate stimulation to the arch of the foot during walking, enhance the user's sense of balance, strengthen foot muscles, and induce proper walking.

[0066] In this way, the golf shoe insole (100) according to the embodiment of the present invention is provided with a second cushion portion (320) to support the side of the forefoot, which is the part where the little toe rests, thereby preventing the foot from tilting outward during a swing and fixing the central axis, so as to improve posture stability and balance, thereby improving hitting accuracy, improving carry and distance, and reducing the angle of direction.

[0067] Hereinafter, with reference to the attached drawings, the effect of swinging after wearing the insole (100) for golf shoes according to an embodiment of the present invention will be explained in more detail.

[0068] The data described below represents the average value after measuring 10 professional and 10 amateur golfers each while wearing the golf shoe insole (100) and while wearing a conventional insole. In the data, the improvement rate (%) is such that 100% represents the same value as the conventional insole, and a value exceeding 100% represents an improved value.

[0069] The body twisting during impact while wearing the above golf shoe insole and a conventional insole is compared and is shown in Table 1 and Figure 7 below.

[0070] Here, the body twisting at impact is a value representing the deviation from the angles of hip abduction, hip internal rotation, knee internal rotation, and ankle external rotation measured multiple times.

[0071] As shown in Table 1 and FIG. 7 below, it can be seen that the angle deviation at each position is reduced when wearing the golf shoe insole (100) according to an embodiment of the present invention. That is, it can be seen that the posture is not disrupted during impact and the impact can be performed with a uniform posture at all times.

[0073] The upper body shaking during a swing while wearing the above golf shoe insole and a conventional insole is compared and is shown in Table 2 and Figure 8 below.

[0074] Here, the upper body sway during the swing is a value representing the distance traveled (mm) from the center of the shoulder. Since the greater the distance traveled, the more the central axis collapses, it is advantageous to reduce the movement of the distance traveled.

[0075] In addition, the upper body shaking during the swing was measured at each of the five stages: address to top back, top back to down, down to impact, impact to follow-through, and follow-through to finish.

[0076] As shown in Table 2 and FIG. 8 below, when wearing the golf shoe insole (100) according to an embodiment of the present invention, it can be seen that the distance traveled from the center of the shoulder is reduced at each stage. That is, it can be seen that the center is not disturbed during the swing and the swing can be performed in a stable posture.

[0078] The movement of the toes after impact while wearing the above golf shoe insole and a conventional insole is compared and is shown in Table 3 and Figure 9 below.

[0079] Here, the toe movement after impact during the above impact is a value represented by measuring the left-right sway of the toes along the central axis.

[0080] As shown in Table 3 and Figure 9 below, it can be seen that the movement of the toes along the central axis is reduced when wearing the insole (100) for golf shoes according to an embodiment of the present invention.

[0081] Generally, after impact, the posture becomes unbalanced and the movement of the pivot foot increases, causing a sway phenomenon (a phenomenon where the center of gravity shifts to the right when the pivot is the left foot).

[0083] The carry, distance, and direction angle of a golf ball after impact were compared with the above golf shoe insole and a conventional insole, as shown in Table 4 and Figure 10 below.

[0084] Here, carry, distance, and direction angle were measured in screen golf, and the direction angle is a value representing the angle of deviation from the set center.

[0085] As shown in Table 4 and FIG. 10 below, when wearing the golf shoe insole (100) according to an embodiment of the present invention, it can be confirmed that the carry and distance are increased and the angle of direction is reduced, allowing for a more accurate strike.

[0087] As described above, when wearing the golf shoe insole (100) according to the embodiment of the present invention, body twisting during impact, upper body shaking during swing, and foot movement after impact can be minimized to maintain a more stable posture, thereby improving the carry and distance of the golf ball after impact and reducing the angle of direction to strike a more accurate location.

[0089] Although the present invention has been described in detail through specific embodiments, this is for the purpose of specifically explaining the invention and is not limited thereto. It is evident that modifications or improvements to the present invention are possible by those skilled in the art within the technical scope of the invention.
