Description

Technology Field

[0001] The present invention relates to a golf shoe sole. Background Technology

[0002] Generally, golf shoes are footwear required to secure traction with the ground during a golf swing, stably support body weight, and maintain balance. In particular, during a golf swing, the load acting on the feet increases due to weight transfer, and torsional and lateral forces occur in combination.

[0003] Conventional golf shoe soles are often formed from a single material or consist of a simple laminated structure, which has the problem of failing to effectively distribute the load generated during a swing and concentrating it in specific areas.

[0004] Consequently, prolonged use not only increased wearer fatigue and difficulty in maintaining a stable posture but also lacked sufficient resistance to torsional forces, leading to unnecessary deformation of the foot during swing motions and consequently reduced accuracy and consistency. Furthermore, there was a limitation in that the balance maintenance function required during weight transfer was not sufficiently secured.

[0005] Meanwhile, the protrusion structure formed on the bottom surface of the sole has a significant impact on grip with the ground, but in conventional technology, the shape and arrangement of the protrusions were simply configured, failing to effectively respond to various ground conditions. Furthermore, strategic placement of the protrusions considering the swing direction and weight transfer path was not sufficiently achieved, so there was a need for improvement in terms of anti-slip and securing propulsion.

[0006] Therefore, there is an increasing technical demand for sole structures that can effectively respond to the complex forces generated during a golf swing while simultaneously improving load support, torsion prevention, and balance maintenance. Prior art literature

[0029] FIG. 1 is an exploded perspective view of a golf shoe sole according to the present invention.

[0030] As shown in FIG. 1, the golf shoe sole may include an outsole (100), a first midsole (200a), a second midsole (200b), a heel bridge (300), a midfoot bridge (400), and one or two insoles.

[0031] The outsole (100) is made of a soft synthetic resin material that is placed at the bottom of the shoe and comes into contact with the ground, and has a plurality of protrusions on its bottom surface.

[0032] The first midsole (200a) is attached and fixed to the upper part of the outsole (100), and the second midsole (200b) is attached and fixed to the upper part of the first midsole (200a).

[0033] A heel bridge (300) and a midfoot bridge (400) are disposed between the first midsole (200a) and the second midsole (200b), and the heel bridge (300) is provided to support a portion of the sidewall of each heel area of ​​the first midsole (200a) and the second midsole (200b), and the midfoot bridge (400) may be provided to support a portion of the sidewall of the mid area of ​​the first midsole (200a) and the second midsole (200b).

[0034] The insole positioned on the upper portion of the second midsole (200b) may include a first insole (500) made of ortholite material attached to the upper surface of the second midsole (200b), and may optionally further include a second insole (600) detachably provided on the upper surface of the first insole (500).

[0035] FIG. 2 is a bottom view of an outsole showing the bottom surface of a golf shoe sole according to the present invention, and FIG. 3 is a bottom perspective view of an outsole showing the bottom surface of a golf shoe sole according to the present invention, wherein ‘inner side of the sole’ in the drawings refers to the right direction based on the left foot (referred to as ‘inner side of the sole’ in the following description), and ‘outer side of the sole’ in the drawings refers to the outer direction of the human body based on the left foot (referred to as ‘outer side of the sole’ in the following description).

[0036] Additionally, the outsole plate (110), the first midsole (200a), and the second midsole (200b) can each be divided into a fore area (100a) that supports the wearer's toes, a mid area (100b) that supports the wearer's midfoot, and a heel area (100c) that supports the wearer's heel.

[0037] The outsole (100) is made of a material having flexibility and elasticity, such as rubber or silicone, and includes an outsole plate (110) that supports the entire sole of the foot, and a plurality of protrusions are formed on the bottom surface of the outsole (100) plate (110).

[0038] The protrusions of the outsole (100) may be arranged in various shapes across the fore area (100a), mid area (100b), and heel area (100c) to simultaneously secure traction and rotational stability, for example, the protrusions may include a first protrusion (120) in the form of diagonal segments arranged to gradually induce and transmit rotational torque in the outward direction, a second protrusion (130) in the form of straight lines formed to decelerate and brake the transmitted torque, a third protrusion (140) in the form of radial lines formed to distribute rotational energy in multiple directions, and a fourth protrusion (150) in the form of sawtooth lines formed to fix the residual torque at the end of rotation by a steep slope on one side corresponding to the direction of torque.

[0039] More specifically, a plurality of first protrusions (120) protruding in the shape of diagonal segmented bars are arranged throughout the entire fore area (100a), the inner edge of the sole of the mid area (100b), and the inner edge of the sole of the heel area (100c), and are provided to control torque during a golf swing motion and for stepwise ground conversion.

[0040] That is, the first projection (120) is arranged diagonally with respect to the pivot zone (an area located on the inner side of the forefoot that serves as the center of rotation) and is formed in a segmented form with multiple bars to transmit and control rotational torque in stages, fixing the body weight during the address and backswing of a golf motion while suppressing slipping and rollover, and improving anti-slip properties during rotation as well as braking force during the downswing and finish sections.

[0041] A second projection (130) protruding in the shape of a straight bar in the front-rear direction of the outsole (100) is arranged in multiple numbers at the outer edge of the sole of the mid area (100b) and the outer edge of the sole of the heel area (100c), and has a stopper function that inhibits movement in the outer direction of the sole.

[0042] That is, the second projection is positioned at the outer edge of the sole relative to the pivot zone and extends in a straight line with respect to the direction of travel, thereby braking the residual torque generated after rotation and ensuring ground stability, which improves braking performance, fixation, and end-stage stability.

[0043] A plurality of radially protruding third protrusions (140) may be arranged between the first protrusion (120) and the second protrusion (130), and may also be arranged at the rear of the heel area (100c). The radially formed third protrusions distribute rotational energy in multiple directions and mediate ground transition to improve the stability of weight transfer and traction during a swing while implementing a non-spike golf shoe.

[0044] The fourth projection (150), which protrudes in a sawtooth shape in the longitudinal cross-section of the outsole plate (110), is arranged lengthwise in the front-rear direction of the outsole (100) in the area between the second projection (130) and the third projection (140).

[0045] That is, the fourth projection (150) is formed such that one side forms a steep slope relative to the torque direction and the other side has a gentle slope, thereby instantaneously locking the residual torque and suppressing reverse slippage.

[0046] Meanwhile, in the mid region (100b) of the outsole plate (110), a first cut (111) cut from the outer end of the sole of the outsole (100) toward the center and a second cut (112) cut from the inner end of the sole of the outsole (100) toward the center are formed in a straight line to facilitate bending deformation in the front-rear direction of the outsole (100), thereby improving flexibility during swing motion.

[0047] The arrangement of the first protrusion (120) and the second protrusion (150) is based on a right-handed wearer, and the protrusions on the golf shoe for a left-handed wearer may be arranged in a reversed left-right orientation. That is, for the golf shoe for a left-handed wearer, the first protrusion (120) may be placed on the outer edge of the sole, while the second protrusion (130) may be placed on the inner edge of the sole.

[0048] FIG. 4 is an exploded perspective view of a key part of a golf shoe sole according to the present invention, FIG. 5 is an outer side view of the sole with the key part components of FIG. 4 combined, and FIG. 6 is an inner side view of the sole with the key part components of FIG. 4 combined.

[0049] As shown in FIGS. 4 to 6, the outsole (100), the first midsole (200a), and the second midsole (200b) are stacked sequentially from bottom to top, and a heel bridge (300) and a midfoot bridge (400) are positioned at the rear and front, respectively, between the first midsole (200a) and the second midsole (200b).

[0050] In the first midsole (200a), a first groove (210) and a second groove (220) are formed to firmly secure the heel bridge (300), and at the same time, a third groove (230), a fourth groove (240), and a fifth groove (250) are formed to firmly secure the midfoot bridge (400).

[0051] The heel bridge (300) is manufactured from a synthetic resin material with higher hardness than the first midsole (200a) and the second midsole (200b) to reinforce the heel area (100c) of the golf shoe sole and to control twisting to maintain balance during a swing motion. It is configured to wrap around each heel area of ​​the first midsole (200a) and the second midsole (200b), including a curved portion (310), an outer heel support portion (320), and an inner heel support portion (330).

[0052] More specifically, the curve portion (310) is formed in an arch shape to be seated on the rear upper surface of the first midsole (200a) and to wrap around the rear wall of the second midsole (200b), the outer heel support portion (320) extends forward from one end of the curve portion (310) to wrap around the outer wall of the heel area of ​​the second midsole (200b), and the inner heel support portion (330) extends forward from the other end of the curve portion (310) to wrap around the inner wall of the heel area of ​​the second midsole (200b).

[0053] A pair of heel outer extensions (321) extend downward from the heel outer support (320), and the pair of heel outer extensions (321) are seated in a pair of first grooves (210) formed on the sole outer wall of the heel area of ​​the first midsole (200a) to support the sole outer wall of the heel area of ​​the first midsole (200a).

[0054] At this time, a first fixing piece (322) is flexibly connected to the lower end of each of the pair of outer heel extensions (321), and the first fixing piece (322) is inserted and fixed between the first midsole (200a) and the outsole (100), thereby improving the bonding ability of the heel bridge (300).

[0055] Likewise, a single inner heel extension (331) extends downward from the inner heel support (330), and the inner heel extension (331) is seated in a second groove (220) formed in the inner sole wall of the heel area of ​​the first midsole (200a) to support the inner sole wall of the heel area of ​​the first midsole (200a).

[0056] At this time, a second fixing piece (332) is flexibly connected to the lower end of the inner extension part (331) of the heel, and the second fixing piece (332) is inserted and fixed between the first midsole (200a) and the outsole (100), thereby improving the bonding ability of the heel bridge (300).

[0057] In this way, the heel bridge (300) has two heel outer extensions (321) formed on the outer side of the sole and one heel inner extension (331) formed on the inner side of the sole. Accordingly, the outer side of the sole has a larger support area than the inner side of the sole, so that rolling and shaking of the outer side of the sole can be suppressed during the landing and finish sections of the heel area during the golf swing motion.

[0058] That is, the two outer heel extensions (321) on the outer side of the sole strongly restrain the shaking and twisting of the outer side of the sole, and the one inner heel extension (331) on the opposite side of the sole assists in balance without excessive rigidity, thereby stabilizing the landing and suppressing rolling of the outer side of the sole.

[0059] The midfoot bridge (400) is manufactured from a synthetic resin material having a higher hardness than the first midsole (200a) and the second midsole (200b), and includes a midfoot plate (410), a pair of transverse protrusions (420), and an outer midfoot support (430) to reinforce the mid area (100b), and is provided to be seated in a plurality of grooves formed in the first midsole (200a) to secure structural rigidity.

[0060] More specifically, the midfoot plate (410) may be interposed between each mid region (100b) of the first midsole (200a) and the second midsole (200b), and a third groove (230) in which the midfoot plate (410) is seated may be formed on the upper surface of the first midsole (200a).

[0061] A pair of transverse protrusions (420) protrude downward in a transverse direction from the bottom surface of the midfoot plate (410), and one end of the pair of transverse protrusions (420) can extend from one side of the midfoot plate (410) to the inner wall surface of the sole of the first midsole (200a), and accordingly, a pair of transverse protrusions (420) are exposed to the outside on the inner surface of the sole as shown in FIG. 6.

[0062] To firmly secure the midfoot plate (410), a pair of fourth grooves (240) on which a transverse protrusion (420) is seated may be formed on the upper surface of the first midsole (200a).

[0063] At the other end of the midfoot plate (410), a midfoot outer support member (430) is extended downward, and the midfoot outer support member (430) is seated in a fifth groove (250) formed on the outer wall of the sole in the mid area of ​​the first midsole (200a) to support the outer wall of the sole in the mid area of ​​the first midsole (200a).

[0064] At this time, a third fixing piece (431) is flexibly connected to the lower end of the midfoot outer support (430), and the third fixing piece (431) is inserted and fixed between the first midsole (200a) and the outsole (100), thereby improving the bonding ability of the midfoot bridge (400).

[0065] Additionally, the transverse protrusion (420) may be provided such that its thickness gradually increases from the outer end of the sole to the inner end of the sole, for example, the thickness of the outer end of the transverse protrusion (420) may be 1.1 mm and the thickness of the inner end of the transverse protrusion (420) may be 1.6 mm.

[0066] In this way, the midfoot bridge (400) is configured such that one midfoot outer support (430) is formed on the outer side of the sole, and the thickness of two transverse protrusions (420) crossing the mid area gradually increases toward the inner side of the sole, thereby reinforcing the entire mid area of ​​the sole while ensuring stability on the inner side of the sole.

[0067] That is, during a golf swing motion, the load of the mid-region, which is responsible for the rotation axis, is stably supported by two horizontal protrusions (420) while distributing the load, and the outer side of the sole forms one midfoot outer support (430) so that the torque transmission after rotation is controlled without excessive rigidity, thereby allowing the center of the mid-region to be maintained and twisted.
