The present invention relates to golf shoes, and specifically, to golf shoes enabling increased driving distance and precise directivity, whereby, in order to enable weight distribution, seating grooves, in which a forefoot portion (ball) and a rearfoot portion (heel) are respectively seated, are respectively formed on the front and rear of the upper surface of an insole, and anti-slip protrusions are respectively formed on one side surface of the front of the upper surface of the insole, and the other side surface of the rear of the upper surface of the insole, so as to prevent the foot from slipping and thus rotating, and thus weight distribution is easily achieved at taking stance and addressing a ball, even by only being grounded on the ground, and the foot is prevented from slipping in the golf shoes at finish, thereby increasing the driving distance of a ball and enhancing the precision of the flying direction of the ball.
These days, the number of golfers in Korea has been soaring, since its popularity is high; Korean golf players are dominant at the international competitions; and interest in health is added.
Golf among ball sports is the only exercise with various courses and surrounding environments, which is the most nearest to the nature and golf courses are extremely wide.
Golf swing sequences are explained briefly as follows. Golf swing is comprised of: a stance positioning both feet with appropriate distance based on a ball; an address for grounding a club immediately behind a ball and making a position for striking a ball; a backswing for bring a club back and then moving it up; a downswing for bringing a club back down in order to strike a ball at backswing; an impact for making a head, moving downward, strike a ball; and a finish for continuously pushing out a ball by movement of inertia after striking a ball, thereby completing a swing.
Among these sequences, as for right-handers, weight shifts to right simultaneously with brining a club back in the backswing, thereby focusing on right foot. At this time, if body is moving in the right direction by failing to support the weight, strong downswing using the weight may not be achieved, thereby failing to swing a ball away, and the body is moving in the right direction toward a ball position, taking an address, thereby reducing precise ball strike. For minimizing adverse effects by moving body position, there have been sustained educations and efforts wherein as a basic position in the golf swing, weight is distributed evenly to both feet for making a swing while taking a stance and an address, thereby maintaining the center of weight in the center of body, and the body is not moved to the right direction while making a right foot acting as a support by putting both joints together.
However, if both joints put together for making a right foot acting as a support while taking a stance and an address, a gap happened between the outer portion of right sole and the ground. Accordingly, if backswing is performed in this condition, weight is moved to the right direction; body is easily and excessively moved outward due to the gap between the outer portion of right golf shoe and the ground, thereby losing a balance; and strong downswing may not be achieved using weight, thereby failing to strike a ball away. Also, if body is moved in the right direction for the ball, taking an address, the accuracy of ball strike is reduced at impact.
At impact, a head of a golf club should strike a ball as exactly as taking address a ball so as to swing the ball away as a golfer has intended. However, as explained on the backswing, if a body may not stand a weight, moving to the right, while backswing, thereby making the body move to the right, and then, the head of the golf club may not strike the ball as exactly as the first addressing status. Also, if downswing is stared for striking the ball, the weight focusing on the right foot moves to the left foot again, the body may not stand the moving weight and move to the left, it may not swing the ball wide because strong swing with the weight may not be achieved until the impact is completed.
Further, if the body moves to the left as for a ball position, taking address, the accuracy of ball strike is reduced at impact.
For minimizing adverse effects by moving body position, there have been sustained educations and efforts wherein the body would not move to the left for maintaining the left wall while joints put together for making the left foot acting as a support while taking a stance and an address. Further, for preventing the center of the body from excessively being moved, if both joints put together for making the left foot acting as a support while taking a stance and an address, a gap happened between the outer portion of left sole and the ground. Accordingly, if downswing is performed in this condition, the weight focusing on the right foot while backswing moves to the left. Then, the body may easily move to the left due to a gap between the outer portion of left golf shoe and the ground, thereby losing control and not standing with strong swing with weight for swinging the ball wide; and if body is moved in the left direction for the ball, taking an address, the accuracy of ball strike is reduced at impact.
A finish stage wherein a swing is completed after impact maintains a hitting power and continuously stabilizes a ball-swing direction. As explained above, the weight focusing on the right foot while backswing moves to the left foot under downswing stage and hit the top level in the finish stage. Hereinafter, if the body may not stand the weight focusing on the left foot and moves to the left, it is not possible to maintain a hitting power and continuously stabilize a ball-swing direction, thereby reducing a ball driving distance(driving distance) and accuracy of a ball-swing direction.
Further, for preventing the above, if both joints put together for making the left foot acting as a support while taking a stance and an address, a gap happened between the outer portion of left sole and the ground. Accordingly, if downswing is performed in this condition, the weight focusing on the right foot while backswing moves to the left. Then, the body may easily move to the left due to a gap between the outer portion of left golf shoe and the ground, thereby losing control and not standing with strong swing with weight for swinging the ball wide; and it is not possible to maintain the stability of a direction of the ball.
As explained above, for preventing sway in which a hitting power of a ball is broken due to excessively left-and-right body movement and accuracy of ball strike is lost, putting both joints together is as a basic position of golf swing.
That is, a complete weight distribution has to be achieved and left foot(or right foot) has to be stably supported for implementing stance, address, and finish perfectly. As for conventional golf shoes, an insole a10-nd a shoe insert are flat and thus, there are problems in that weight distribution is not easy while taking stand and address; a foot is not stable in the golf shoes in the finish stage; and there is a rotation based on a foot arch while being moving outward.

Further, the other object of the present invention is to provide the golf shoes enabling increased driving distance and precise directivity, wherein hollow holes are formed in seating grooves, thereby reducing weight to an insole for having relatively weak repulsive power and absorbing shocks, and resilient members are formed in front seating grooves, thereby boosting power while golf impact by repulsive power of the resilient members while downswinging.

Referring to
First, an outsole(10, sole), of synthetic resins like urethane, synthetic rubber, is equipped with a plurality of spikes at the bottom. Hereinafter, it is desirable to form a height of external spikes higher than that of inner spikes for preventing swaying.
Further, an insole(20), of synthetic resins like urethane, is bonded to an upper side of the outsole(10) and comprises: in order to enable weight distribution on the front and rear based on midfoot(arch), round first and second seating grooves(21, 22), in which a forefoot portion (ball) and a rearfoot portion (heel) are respectively seated on the front and rear of the upper surface, are respectively formed on the front and rear of the upper surface of an insole; and round anti-slip protrusions(23) are respectively formed on one side surface of the front of the upper surface, and the other side surface of the rear of the upper surface. Hereinafter, in the insole(20), a round foot arch member(24) is protruded to a location that corresponds to the midfoot.
Further, the first and second seating grooves(21, 22) of the insole(20) are comprised of hollow holes(25) so as to form relatively weak repulsive power by reducing weight, thereby absorbing shocks, wherein the first seating grooves(21) are further deeper formed than the second seating grooves(22) in order to more distribute weight on the second seating grooves(22)(e.g., 45%, the front, 55%, the rear), and resilient members(26) are inserted in the first seating grooves(21) based on the hollow holes(25) in order to increase repulsive power on downswing. Hereinafter, the hollow holes(25) may be hexagonal, octagonal, rectangular, round, etc. As for the resilient members(26), of coil springs, it is desirable to be formed on the right only in case of right supporting foot, and to be formed on the left only in case of left supporting foot, but it may be formed on both cases selectively.
Further, it is desirable that the outer side of the first seating grooves(21) of the insole(20) is formed higher relatively, so as to prevent the balls being pushed out, and the inner side of the second seating grooves(22) is formed higher relatively, so as to prevent the balls being pushed in.
Continuously, a shoe insert(30) is stacked to the upper surface of the insole(20); supplementary seating grooves(31) are formed to a location that corresponds to the first and second seating grooves(21, 22); and a supplementary anti-slip protrusion(33) is formed to a location that corresponds to the anti-slip protrusions(23) of the insole(20). Hereinafter, it is desirable that the supplementary seating grooves(31) and the supplementary anti-slip protrusion(33) may be manufactured in large quantity by a same size; pressure of a user's foot is measured by a foot pressure analyzer at addressing the ball; and it may be changed to be corresponded to ground areas and pressure by analyzing swing positions with a swing analyzer. Further, it is desirable to form a supplementary foot arch member(35) for being formed in a location that corresponds to the foot arch member(24) of the insole(20) and cover.
Continuously, uppers(40), bonded between the bottom edge of the insole(20) and the edge of the outsole(10), form appearance of golf shoes.
Hereinafter, the constitution of golf shoes enabling increased driving distance and precise directivity according to the present invention will be described in detail with the accompanying drawings.
When a user wears golf shoes(1), foot arch members(24), protruded from the insole(20), are inserted to the midfoot of a user, fixing the midfoot.
Simultaneously, the forefoot portion and the rearfoot portion are respectively fixed to the first and second seating grooves(21, 22) of the insole(20).
As long as the forefoot portion and the rearfoot portion are fixed to the first and second seating grooves(21, 22) of the insole(20), weight distribution is easily achieved by the depths of the first and second seating grooves(21, 22).
That is, since a user wears golf shoes(1), weight distribution is easily achieved by being grounded on the ground at addressing a ball and thus, additional motions for weight distributions are not necessary.
Meanwhile, the forefoot portion and the rearfoot portion in the user's foot are fixed to the first and second seating grooves(21, 22) of the insole(20), and front outside and back inside of a foot are supported by anti-slip protrusions(23) of the insole(20).
Then, while swinging, the foot in the golf shoes(1) are not slipped by anti-slip protrusions(23), thereby increasing driving distance and enabling precise directivity.
Further, while swinging, the pressure applying to the foot is absorbed by hollow holes(25) in the first and second seating grooves(21, 22) of the insole(20). While downswinging, elastic rebound is generated in the resilient members(26), inserted to the first seating grooves(21), thereby boosting repulsive power and increasing driving distance with raised power while golf impact.
Meanwhile, when the user walks long in golf game, shock is absorbed in the first and second seating grooves(21, 22) and elasticity is generated in the resilient members(26), thereby decreasing foot fatigue and preventing reduced stamina.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
