[0032] Hereinafter, a shoe plate and a sole including the shoe plate according to an embodiment of the utility model will be described in detail with reference to the accompanying drawings. The terms used in this specification include terms used to appropriately express preferred embodiments of the utility model, and may vary according to the intention of a user or operator or the habits of the field to which the utility model belongs. Therefore, the definition of the terms of the utility model should be based on the content of the entire specification.

[0033] Figure 1 and Figure 2 is an exploded perspective view of a sole according to an embodiment of the utility model, wherein Figure 1 It is a top view. Figure 2 It is a bottom view. Figure 3 It is a perspective view of a sole according to one embodiment of the utility model. Figure 4 and Figure 5 Is set in Figure 1 A plan view and a side view of a shoe plate according to a first embodiment of the present invention on a sole.

[0034] refer to Figures 1 to 5 A sole 1A according to one embodiment of the present invention includes a shoe plate 10 and midsole parts 150 and 170 in close contact with the shoe plate 10. The sole 1A is coupled to the outer periphery of an upper (not shown) surrounding a wearer's foot, supports the sole of the wearer's foot, and contacts the ground.

[0035] The shoe plate 10 is a plate-shaped member and includes a support body 11, a forefoot portion 13 and a rearfoot portion 30. The forefoot portion 13 extends from the support body 11 in one direction, specifically, forward, and the rearfoot portion 30 extends from the support body 11 in another direction, specifically, backward. The support body 11, the forefoot portion 13 and the rearfoot portion 30 are formed to be connected as one piece.

[0036] The forefoot portion 13 includes forefoot balance stabilizing portions 14 and 17 and propulsion ensuring portions 20 and 23. The forefoot balance stabilizing portions 14 and 17 diverge from the support body 11 and extend forward. The propulsion ensuring portions 20 and 23 diverge from the support body 11 and extend forward while being spaced apart from the forefoot balance stabilizing portions 14 and 17.

[0037] The forefoot balance stabilizing portions 14 and 17 may include a first forefoot balance stabilizing portion 14 and a second forefoot balance stabilizing portion 17. The first forefoot balance stabilizing portion 14 may be disposed on the outside of the propulsion ensuring portions 20 and 23 in a direction toward the width of the foot of the shoe wearer, and the second forefoot balance stabilizing portion 17 may be disposed on the inside of the propulsion ensuring portions 20 and 23 in a direction toward the width of the foot of the shoe wearer.

[0038] Here, toward the outside in the width direction of the foot may be a side relatively far from the other foot wearing the shoe sole 1A, and toward the inside in the width direction of the foot may be a side relatively close to the other foot wearing the shoe sole 1A.

[0039] The first forefoot balance stabilization portion 14 and the second forefoot balance stabilization portion 17 may extend from the support body 11 to bend gently downward and then bend gently upward again. Therefore, the end 15 of the first forefoot balance stabilization portion 14 and the end 18 of the second forefoot balance stabilization portion 17 in the longitudinal direction may be at a higher level than the support body 11, and the middle part of the first forefoot balance stabilization portion 14 and the second forefoot balance stabilization portion 17 in the longitudinal direction may be at a level slightly lower than the support body 11.

[0040] The advancement ensuring parts 20 and 23 include a first advancement ensuring part 20 and a second advancement ensuring part 23 that are bifurcated from the support body 11, are spaced apart from each other and extend forward to have a curved surface. To ensure advancement, the levels of the first advancement ensuring part 20 and the second advancement ensuring part 23 can be lowered from the support body 11 along the extension direction and then raised.

[0041] The first propulsion ensuring portion 20 and the second propulsion ensuring portion 23 are arranged between the first forefoot balance stabilizing portion 14 and the second forefoot balance stabilizing portion 17. The first forefoot balance stabilizing portion 14 and the second forefoot balance stabilizing portion 17 extend to different levels from the first propulsion ensuring portion 20 and the second propulsion ensuring portion 23. Figure 5 As shown, the first propulsion ensuring portion 20 and the second propulsion ensuring portion 23 may be formed at a lower level than the first forefoot balance stabilizing portion 14 and the second forefoot balance stabilizing portion 17 .

[0042] In addition, in order to ensure propulsion, the horizontal planes of the first propulsion ensuring portion 20 and the second propulsion ensuring portion 23 may be lowered in the extension direction from the support body 11 and then raised. Specifically, compared with the first forefoot balance stabilizing portion 14 and the second forefoot balance stabilizing portion 17, the first propulsion ensuring portion 20 and the second propulsion ensuring portion 23 may extend to bend more sharply downward from the support body 11 and then bend more sharply upward again.

[0043] Therefore, the level of the middle portion of the first propulsion ensuring portion 20 and the second propulsion ensuring portion 23 in the longitudinal direction is lower than the level of the middle portion of the first forefoot balance stabilizing portion 14 and the second forefoot balance stabilizing portion 17. At the same time, the level of the end portion 21 of the first propulsion ensuring portion 20 and the end portion 24 of the second propulsion ensuring portion 23 in the longitudinal direction is lower than or equal to the level of the end portion 15 of the first forefoot balance stabilizing portion 14 and the end portion 18 of the second forefoot balance stabilizing portion 17 in the longitudinal direction.

[0044] The forefoot portion 13 may further include a first weight reduction portion 26 disposed between the forefoot balance stabilizing portions 14, 17 and the propulsion ensuring portions 20, 23 to reduce the weight of the shoe plate 10. The first weight reduction portion 26 may be an empty space disposed between the forefoot balance stabilizing portions 14, 17 and the propulsion ensuring portions 20, 23. Specifically, a pair of first weight reduction portions 26 may be disposed between the first forefoot balance stabilizing portion 14 and the first propulsion ensuring portion 20 and between the second forefoot balance stabilizing portion 17 and the second propulsion ensuring portion 23.

[0045] In addition, the forefoot portion 13 may further include a second weight reduction portion 27 disposed between the first propulsion ensuring portion 20 and the second propulsion ensuring portion 23 to reduce the weight of the shoe plate 10. Like the first weight reduction portion 26, the second weight reduction portion 27 may be an empty space disposed between the first propulsion ensuring portion 20 and the second propulsion ensuring portion 23.

[0046] The rearfoot portion 30 may further include a first rearfoot balance stabilizing portion 31 and a second rearfoot balance stabilizing portion 33. The first rearfoot balance stabilizing portion 31 and the second rearfoot balance stabilizing portion 33 may each diverge from the support body 11, may extend rearward, and may be spaced apart from each other. The first rearfoot balance stabilizing portion 31 may be disposed at an outer portion in a direction toward the width of a foot of a shoe wearer, and the second rearfoot balance stabilizing portion 33 may be disposed at an inner portion in a direction toward the width of a foot of a shoe wearer.

[0047] Here, the outer portion in the width direction of the shoe wearer's foot may be a side relatively away from the other foot wearing the sole 1A in the direction of the width of the foot, and the inner portion in the width direction of the shoe wearer's foot may be a side relatively close to the other foot wearing the sole 1A in the direction of the width of the foot.

[0048] The shoe plate 10 may further include an impact reduction portion 35 disposed between the first rearfoot balance stabilizing portion 31 and the second rearfoot balance stabilizing portion 33 to reduce the impact applied to the heel of the shoe wearer when the shoe wearer walks or runs. Specifically, the impact reduction portion 35 may be an empty space disposed between the first rearfoot balance stabilizing portion 31 and the second rearfoot balance stabilizing portion 33.

[0049] The midsole parts 150 and 170 may include an upper midsole part 50 and a lower midsole part 170. The upper midsole part 150 supports the sole of the shoe wearer. The upper midsole part 150 may be in close contact with the upper surface of the support body 11, the upper surfaces of the first forefoot balance stabilizing part 14 and the second forefoot balance stabilizing part 17, the upper surfaces of the first propulsion ensuring part 20 and the second propulsion ensuring part 23, and the upper surface of the rearfoot part 30 (specifically, the upper surfaces of the first rearfoot balance stabilizing part 31 and the second rearfoot balance stabilizing part 33).

[0050] The lower surface of the upper midsole portion 150 may include: a support body contact surface 152 that is in close contact with the upper surface of the support body 11; a first forefoot balance stabilizing portion contact surface 153 and a second forefoot balance stabilizing portion contact surface 154 that are in close contact with the upper surfaces of the first forefoot balance stabilizing portion 14 and the second forefoot balance stabilizing portion 17; a propulsion ensuring portion contact surface 155 that is in close contact with the upper surfaces of the first propulsion ensuring portion 20 and the second propulsion ensuring portion 23 and gradually protrudes downward from the first forefoot balance stabilizing portion contact surface 153 and the second forefoot balance stabilizing portion contact surface 154; a first rear foot balance stabilizing portion contact surface 157 and a second rear foot balance stabilizing portion contact surface 158 that are in close contact with the upper surfaces of the first rear foot balance stabilizing portion 31 and the second rear foot balance stabilizing portion 33; and a lower midsole contact surface 159 arranged between the first rear foot balance stabilizing portion contact surface 157 and the second rear foot balance stabilizing portion contact surface 158.

[0051] The lower midsole portion 170 can be positioned below the upper midsole portion 150 and can be in close contact with the lower surface of the support body 11, the lower surfaces of the first forefoot balance stabilization portion 14 and the second forefoot balance stabilization portion 17, the lower surfaces of the first propulsion ensuring portion 20 and the second propulsion ensuring portion 23, and the lower surface of the rearfoot portion 30 (specifically, the lower surfaces of the first rearfoot balance stabilization portion 31 and the second rearfoot balance stabilization portion 33).

[0052] The upper surface of the lower midsole portion 170 may include: a support body contact surface 171 that is in close contact with the lower surface of the support body 11; a first forefoot balance stabilizing part contact surface 175 and a second forefoot balance stabilizing part contact surface 176 that are in close contact with the lower surfaces of the first forefoot balance stabilizing part 14 and the second forefoot balance stabilizing part 17; a first propulsion ensuring part contact surface 177 and a second propulsion ensuring part contact surface 178 that are in close contact with the lower surfaces of the first propulsion ensuring part 20 and the second propulsion ensuring part 23; and a first rear foot balance stabilizing part contact surface 185 and a second rear foot balance stabilizing part contact surface 186 that are in close contact with the lower surfaces of the first rear foot balance stabilizing part 31 and the second rear foot balance stabilizing part 33.

[0053] In addition, the upper surface of the lower midsole portion 170 may also include: a first forefoot upper midsole contact surface 179, a second forefoot upper midsole contact surface 180 and a third forefoot upper midsole contact surface 181, which pass through the forefoot portion 13 in the thickness direction of the shoe plate 10 and directly contact the lower surface of the upper midsole portion 150; and a rearfoot upper midsole contact surface 187, which passes through the rearfoot portion 30 in the thickness direction of the shoe plate 10 and directly contact the lower surface of the upper midsole portion 150.

[0054] Specifically, the first forefoot upper midsole contact surface 179 passes through the second weight reduction portion 27 and gradually protrudes upward to contact the propulsion ensuring portion contact surface 155 of the upper midsole portion 150, and the second forefoot upper midsole contact surface 180 and the third forefoot upper midsole contact surface 181 pass through the pair of first weight reduction portions 26 and gradually protrude upward to contact the propulsion ensuring portion contact surface 155 of the upper midsole portion 150. The rearfoot upper midsole contact surface 187 passes through the impact reduction portion 35 and gradually protrudes upward to contact the lower midsole contact surface 159 of the upper midsole portion 150.

[0055] The upper midsole portion 150 and the lower midsole portion 170 may be made of, for example, a material such as a foam resin that is lightweight and easily elastically deformed by a relatively small external force. The shoe plate 10 may be made of a material having a higher elastic modulus than the material of the upper midsole portion 150 and the lower midsole portion 170. In addition, the shoe plate 10 may have a greater hardness and a greater specific gravity than the material of the upper midsole portion 150 and the lower midsole portion 170.

[0056] Therefore, when the shoe wearer steps on an uneven ground with protrusions or grooves, for example, through the outer portion or the inner portion in the direction from the sole 1A to the width of the foot, the portion of the lower midsole portion 170 overlapping the forefoot balance stabilizing portions 14 and 17 (separated from the propulsion ensuring portions 20 and 23) can be greatly squeezed, and at the same time, the forefoot balance stabilizing portions 14 and 17 can be greatly deformed in the vertical direction. Therefore, the angle of the sole 1A and the angle of the ankle of the shoe wearer are not excessively bent. Therefore, the shoe plate 10 and the sole 1A including the shoe plate 10 have improved balance stability performance, thereby allowing the shoe wearer to maintain balance.

[0057] Furthermore, when the shoe wearer walks or runs, the propulsion ensuring portions 20 and 23 of the shoe plate 10 bend upward in the ascending direction relative to the support body 11, and then elastically return to their original shapes at the moment when the front end of the sole 1A leaves the ground, thereby accelerating the shoe wearer forward. Therefore, the shoe plate 10 and the sole 1A including the shoe plate 10 have improved propulsion performance to help the shoe wearer walk or run quickly with less energy.

[0058] At the same time, like the propulsion ensuring portions 20 and 23, when the shoe wearer walks or runs, the forefoot balance stabilizing portions 14 and 17 also bend upward in the ascending direction relative to the support body 11, and then elastically return to their original shapes at the moment when the front end of the sole 1A leaves the ground. Therefore, the forefoot balance stabilizing portions 14 and 17 contribute to improving the propulsion performance as do the propulsion ensuring portions 20 and 23. Therefore, by means of the propulsion ensuring portions 20 and 23 and the forefoot balance stabilizing portions 14 and 17, the propulsion performance of the shoe plate 10 can be more significantly improved. However, the amount of elastic deformation of the forefoot balance stabilizing portions 14 and 17 can be less than the amount of elastic deformation of the propulsion ensuring portions 20 and 23.

[0059] In addition, even when the shoe wearer's heel lands unstably through the sole 1A, the first rear foot balance stabilization portion 31 and the second rear foot balance stabilization portion 33 can reduce the degree of ankle bending caused by the unstable landing and can significantly improve its balance stability performance, thereby allowing the shoe wearer to maintain balance.

[0060] At the same time, since the rear foot upper midsole contact surface 187 of the lower midsole portion 170 passes through the impact reduction portion 35 and contacts the lower midsole contact surface 159 of the upper midsole portion 150, the cushioning performance is significantly improved when the wearer's heel touches the ground through the sole 1A, which reduces the impact applied to the foot and leg.

[0061] In addition, since the first and second weight reducing portions 26, 27 and the impact reducing portion 35 are formed through the thickness of the shoe plate 10, the volume of the shoe plate 10 having a greater specific gravity than the upper midsole portion 150 and the lower midsole portion 170 is reduced, and thus the total weight of the sole 1A is reduced.

[0062] The sole 1A may further include an outsole portion 190 that is stacked below the lower midsole portion 170 and contacts the ground. The outsole portion 190 may include a forefoot outer outsole 191, a forefoot inner and outer outsole 192, and first and second rearfoot outsoles 193 and 194 that are spaced apart from each other.

[0063] The forefoot outer outsole 191 is substantially vertically aligned with and overlaps the first forefoot balance stabilizing portion 14 and the second forefoot balance stabilizing portion 17, and is connected in a V-shape. The forefoot inner and outer outsole 192 is partially vertically aligned with and overlaps the first and second propulsion ensuring portions 20 and 23, and is separated and spaced from the forefoot outer outsole 191. The first and second rearfoot outer outsole 193 and 194 are partially vertically aligned with and overlaps the first and second rearfoot balance stabilizing portions 158 and 159, and are separated and spaced from each other.

[0064] The shoe plate 10 may further include reinforcement portions 36 and 38 for reinforcing the rigidity of the portions where the propulsion ensuring portions 20 and 23 are connected to the support body 11. Since the propulsion ensuring portions 20 and 23 are repeatedly bent and straightened relative to the support body 11, the reinforcement portions 36 and 38 are provided to reinforce the rigidity of the boundaries between the propulsion ensuring portions 20, 23 and the support body 11, and also to improve the propulsion force of the shoe plate 10.

[0065] The reinforcement parts 36 and 38 may include a protruding rib that protrudes from the lower surface of the shoe plate 10 and is connected to the propulsion securing parts 20 and 23 and the support body 11 at one side and the other side thereof in the longitudinal direction. Specifically, the reinforcement parts 36 and 38 may include a first reinforcement part 36 and a second reinforcement part 38.

[0066] The front end of the first reinforcing portion 36 may be connected to the lower surface of the first propulsion ensuring portion 20, and the rear end of the first reinforcing portion 36 may be connected to the lower surface of the support body 11. The front end of the second reinforcing portion 38 may be connected to the lower surface of the second propulsion ensuring portion 23, and the rear end of the second reinforcing portion 38 may be connected to the lower surface of the support body 11. The first reinforcing portion 36 and the second reinforcing portion 38 may be spaced apart from each other.

[0067] at the same time, Figure 2 and Figure 3 The reinforcement portions 36 and 38 shown are exemplary, and various reinforcement portions with different shapes may be provided in the shoe plate of the present invention. For example, the reinforcement portion may extend in a curved manner in a direction toward the width of the foot, particularly in the medial or lateral direction. Alternatively, the reinforcement portion may extend along a straight path. Alternatively, the reinforcement portion may extend along a U-shaped path to connect from the propulsion ensuring portions 20 and 23 to the forefoot balance stabilizing portions 14 and 17 through the support body 11. Alternatively, the reinforcement portion may extend along a U-shaped path to connect from the first propulsion ensuring portion 20 to the second propulsion ensuring portion 23 through the support body 11.

[0068] The lower midsole portion 170 may further include a first reinforcement portion avoidance groove 172 and a second reinforcement portion avoidance groove 173, which are recessed to accommodate the first reinforcement portion 36 and the second reinforcement portion 38. Due to the first reinforcement portion avoidance groove 172 and the second reinforcement portion avoidance groove 173, the first reinforcement portion 36 and the second reinforcement portion 38 are not restricted from contacting the lower midsole portion 170, and the lower midsole portion 170 may also not be damaged by the first reinforcement portion 36 and the second reinforcement portion 38.

[0069] Figure 6 is a side view of a sole according to another embodiment of the utility model, the sole comprising Figure 5 Reference Figure 6 According to another embodiment of the present invention, the sole 1B may include a shoe plate 10, midsole parts 210, 220 and 225 in close contact with the shoe plate 10, and an outsole part 230 in contact with the ground. Figures 1 to 5 The shoe plate 10 according to the first embodiment of the present invention provided in the described shoe sole 1A is the same and is given the same reference numerals, so redundant description will be omitted.

[0070] The midsole parts 210, 220, and 225 may include an upper midsole part 21, a front lower midsole part 220, and a rear lower midsole part 225. The upper midsole part 210 may support the sole of the shoe wearer. The lower surface of the upper midsole part 210 may be in close contact with the upper side of the support body 11, the upper surfaces of the forefoot balance stabilizing parts 14 and 17, and the upper surface of the rearfoot part 30.

[0071] The front lower midsole portion 220 may be positioned below the upper midsole portion 210 and may be interposed between the forefoot balance stabilizing portions 14, 17 and the propulsion ensuring portions 20, 23 to be in close contact with the lower surfaces of the forefoot balance stabilizing portions 14, 17 and the upper surfaces of the propulsion ensuring portions 20, 23. The front lower midsole portion 220 may include a first midsole piece 221 and a second midsole piece 223 that are separated from each other.

[0072] The first midsole member 221 may be arranged in front of the second midsole member 223. The portion of the sole 1B that is repeatedly bent and straightened when the shoe wearer walks or runs may be pre-divided into the first midsole member 221 and the second midsole member 223, thereby preventing damage to the front lower midsole portion 220 and a reduction in durability due to the damage. Figure 6 In the embodiment, the front lower midsole portion 220 is configured to be divided into a pair of midsole pieces 221 and 223, but the present invention is not limited thereto. The front lower midsole portion 220 may be divided into a greater number of midsole pieces.

[0073] The rear lower midsole portion 225 may be positioned below the upper midsole portion 210 and may be in close contact with the lower surface of the rearfoot portion 30. The midsole portions 210, 220, and 225 may be made of, for example, a material such as a foam resin that is lightweight and easily elastically deformed by a relatively small external force.

[0074] Figure 7 and Figure 8 It is a plan view of a shoe plate according to the second embodiment and the third embodiment of the utility model. Figure 7 The shoe plate 40 and the shoe plate 41 according to the second embodiment of the present invention are shown in FIG. Figure 8 The shoe plate 70 according to the third embodiment of the present invention shown can be provided in the shoe sole 1A instead of the shoe plate 10 according to the first embodiment of the present invention.

[0075] Reference together Figure 1 , Figure 2 , Figure 5 and Figure 7 The shoe plate 40 according to the second embodiment of the present utility model is a plate-shaped member and includes a support body 41, a forefoot portion 43 and a rear foot portion 60. The forefoot portion 43 extends from the support body 41 in one direction, specifically, forward, and the rear foot portion 60 extends from the support body 41 in another direction, specifically, backward. The support body 41, the forefoot portion 43 and the rear foot portion 60 are formed to be connected as one piece.

[0076] The forefoot portion 43 includes forefoot balance stabilizing portions 44 and 47 and a propulsion ensuring portion 50. The forefoot balance stabilizing portions 44 and 47 diverge from the support body 41 to extend forward. The propulsion ensuring portion 50 diverges from the support body 41 and extends forward to be spaced apart from the forefoot balance stabilizing portions 44 and 47.

[0077] The forefoot balance stabilizing portions 44 and 47 may include a first forefoot balance stabilizing portion 44 and a second forefoot balance stabilizing portion 47. The first forefoot balance stabilizing portion 44 may be disposed on the outside of the propulsion ensuring portion 50 in a direction toward the width of the shoe wearer's foot, and the second forefoot balance stabilizing portion 47 may be disposed on the inside of the propulsion ensuring portion 50 in a direction toward the width of the shoe wearer's foot.

[0078] Here, toward the outside in the width direction of the foot may be a side relatively far from the other foot wearing the shoe sole 1A, and toward the inside in the width direction of the foot may be a side relatively close to the other foot wearing the shoe sole 1A.

[0079] The first forefoot balance stabilizing portion 44 and the second forefoot balance stabilizing portion 47 may extend from the support body 41 to bend slightly downward and then bend slightly upward again. Therefore, the end 45 of the first forefoot balance stabilizing portion 44 and the end 48 of the second forefoot balance stabilizing portion 47 in the longitudinal direction may be at a higher level than the support body 41, and the middle portions of the first forefoot balance stabilizing portion 44 and the second forefoot balance stabilizing portion 47 in the longitudinal direction may be at a level slightly lower than the support body 41.

[0080] The propulsion ensuring portion 50 is disposed between the first forefoot balance stabilizing portion 44 and the second forefoot balance stabilizing portion 47. The first forefoot balance stabilizing portion 44 and the second forefoot balance stabilizing portion 47 extend to a different level from the propulsion ensuring portion 50. Figure 5 In the shoe plate 10 according to the first embodiment of the present invention shown, the propulsion ensuring portion 50 may be formed at a lower level than the first forefoot balance stabilizing portion 44 and the second forefoot balance stabilizing portion 47 .

[0081] The propulsion securing portion 50 diverges from the support body 41 and extends forward to have a curved surface. In order to ensure propulsion, the level of the propulsion securing portion 50 may be lowered along the extension direction from the support body 41 and then raised. Specifically, compared with the first forefoot balance stabilizing portion 44 and the second forefoot balance stabilizing portion 47, the propulsion securing portion 50 may extend to bend more sharply downward from the support body 41 and then bend more sharply upward again.

[0082] The forefoot portion 43 may further include a pair of first weight reduction portions 53 disposed between the pair of forefoot balance stabilizing portions 44, 47 and the propulsion ensuring portion 50 to reduce the weight of the shoe plate 40. The first weight reduction portion 53 may be an empty space disposed between the forefoot balance stabilizing portions 44, 47 and the propulsion ensuring portion 50.

[0083] In addition, the forefoot portion 43 may further include a second weight-reducing portion 55 that passes through the propulsion ensuring portion 50 in the thickness direction and is disposed in the propulsion ensuring portion 50 to reduce the weight of the shoe plate 40. Specifically, the second weight-reducing portion 55 may be a through hole. However, the second weight-reducing portion 55 is not limited to having Figure 7 The through hole of the shape shown in the figure may be a plurality of through holes spaced apart from the advancement ensuring portion 50. Figure 7 Unlike shown, the propulsion securing portion 50 may not include the second weight reducing portion 55 in the form of a through hole.

[0084] The rearfoot portion 60 may further include a first rearfoot balance stabilizing portion 61 and a second rearfoot balance stabilizing portion 63 that are spaced apart from each other, and an impact reduction portion 65 that is disposed between the first rearfoot balance stabilizing portion 61 and the second rearfoot balance stabilizing portion 63. Since the first rearfoot balance stabilizing portion 61, the second rearfoot balance stabilizing portion 63, and the impact reduction portion 65 have the same shape and function as the first rearfoot balance stabilizing portion 31, the second rearfoot balance stabilizing portion 33, and the impact reduction portion 35 of the shoe plate 10 according to the first embodiment, redundant description will be omitted.

[0085] Reference together Figure 1 , Figure 2 , Figure 5 and Figure 8 The shoe plate 70 according to the third embodiment of the present utility model is a plate-shaped member and includes a support body 71, a forefoot portion 73 and a rear foot portion 90. The forefoot portion 73 extends from the support body 71 in one direction, specifically, forward, and the rear foot portion 90 extends from the support body 71 in another direction, specifically, backward. The support body 71, the forefoot portion 73 and the rear foot portion 90 are formed to be connected as one body.

[0086] The forefoot portion 73 may include forefoot balance stabilizing portions 74 and 77, propulsion ensuring portions 80 and 83, and weight reducing portions 86 and 87. The forefoot balance stabilizing portions 74 and 77 may include a first forefoot balance stabilizing portion 74 and a second forefoot balance stabilizing portion 77. The propulsion ensuring portions 80 and 83 may include a first propulsion ensuring portion and a second propulsion ensuring portion 83. The weight reducing portions 86 and 87 may include a first weight reducing portion 86 and a second weight reducing portion 87.

[0087] Since the first forefoot balance stabilization portion 74, the second forefoot balance stabilization portion 77, the first propulsion ensuring portion 80, the second propulsion ensuring portion 83, the first weight reducing portion 86 and the second weight reducing portion 87 have the same shape and function as the first forefoot balance stabilization portion 14, the second forefoot balance stabilization portion 17, the first propulsion ensuring portion 20, the second propulsion ensuring portion 23, the first weight reducing portion 26 and the second weight reducing portion 27 of the shoe plate 10 according to the first embodiment of the present utility model, redundant description will be omitted.

[0088] The rear foot portion 90 may be branched and extended rearward from the support body 71. The rear foot portion 90 may include a rear foot balance stabilizing portion 91 and a shock mitigating portion 95. Even when the heel of the shoe wearer lands unstably through the sole 1A, the rear foot balance stabilizing portion 91 may reduce the degree of ankle bending caused by the unstable landing and may allow the shoe wearer to maintain balance.

[0089] The impact reduction portion 95 may pass through the rear foot portion 90 in the thickness direction and may be disposed inside the rear foot portion 90. Specifically, the impact reduction portion 95 may be a through hole. Since the upper midsole portion 150 and the lower midsole portion 170 are in direct contact by passing through the impact reduction portion 95, when the heel of the shoe wearer touches the ground through the sole 1A, the cushioning performance that reduces the impact applied to the foot and leg can be significantly improved.

[0090] Fig. 9 2 is a side view of a shoe plate according to a fourth embodiment of the present invention. Figure 5 and Fig. 9 The shoe plate 100 according to the fourth embodiment of the present utility model may be a plate-shaped member, and may include a support body 101, a forefoot portion 103 extending forward from the front support body 101, a rearfoot portion 120 extending rearward from the support body 101, and reinforcement portions 126 and 128. The support body 101, the forefoot portion 103, the rearfoot portion 120, and the reinforcement portions 126 and 128 are formed to be connected as one piece.

[0091] Like the forefoot portion 13 of the shoe plate 10 according to the first embodiment of the present invention, the forefoot portion 103 may include a first forefoot balance stabilizing portion 104 and a second forefoot balance stabilizing portion 107, a first propulsion ensuring portion 110 and a second propulsion ensuring portion 113, and a first weight reduction portion and a second weight reduction portion (not shown). Figure 5 Unlike the first forefoot balancing stabilizing portion 14 and the second forefoot balancing stabilizing portion 17 of the shoe plate 10 according to the first embodiment of the present invention, the first forefoot balancing stabilizing portion 104 and the second forefoot balancing stabilizing portion 107 may be formed at a higher level than the support body 101 .

[0092] The first propulsion ensuring portion 110 and the second propulsion ensuring portion 113 may be formed at a lower level than the first forefoot balance stabilizing portion 104 and the second forefoot balance stabilizing portion 107. Like the first weight saving portion 26 and the second weight saving portion 27 of the shoe plate 10 according to the first embodiment of the present invention, the shoe plate 100 according to the fourth embodiment of the present invention may further include: a pair of first weight saving portions (not shown) disposed between the first forefoot balance stabilizing portion 104 and the first propulsion ensuring portion 110 and between the second forefoot balance stabilizing portion 107 and the second propulsion ensuring portion 113; and a second weight saving portion (not shown) disposed between the first propulsion ensuring portion 110 and the second propulsion ensuring portion 113.

[0093] Like the rear foot portion 30 of the shoe plate 10 according to the first embodiment of the present invention, the rear foot portion 120 may also include a first rear foot balance stabilization portion (not shown) and a second rear foot balance stabilization portion (not shown) spaced apart from each other, and an impact reduction portion (not shown) arranged between the first rear foot balance stabilization portion and the second rear foot balance stabilization portion.

[0094] Like the reinforcing portions 36 and 38 of the shoe plate 10 according to the first embodiment of the present invention, the reinforcing portions 126 and 128 of the shoe plate 100 according to the fourth embodiment of the present invention may be provided to reinforce the propulsion of the propulsion ensuring portions 110 and 113 and the rigidity of the shoe plate 100 at the portion where the propulsion ensuring portions 110, 113 are connected to the support body 101. The reinforcing portions 126 and 128 may be formed to protrude from the lower surface of the boundary between the propulsion ensuring portions 110, 113 and the support body 101.

[0095] The present application has been described with reference to the embodiments shown in the accompanying drawings, but this is merely illustrative and those skilled in the art will appreciate that various modifications and other equivalent embodiments may be made therefrom.

[0096] For example, Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 The shoe plate shown includes one propulsion ensuring portion or a pair of propulsion ensuring portions. Alternatively, the shoe plate may include three or more propulsion ensuring portions. In addition, Figure 1 , Figure 2 , Figure 4 and Figure 7The shoe plate shown includes a pair of rear foot balancing stabilizing portions disposed at each of the medial and lateral sides in a direction toward the width of the foot. Alternatively, the shoe plate may include only one rear foot balancing portion at one of the medial and lateral sides.

[0097] The shoeboard of the utility model includes a forefoot balance stabilization portion and a propulsion ensuring portion, which are connected to the main body and separated from each other. Therefore, even when the shoe wearer steps on an uneven ground with protrusions or grooves, for example, through the outer portion or the inner portion in the direction from the sole to the width of the foot, the propulsion ensuring portion and the forefoot balance stabilization portion separated from the propulsion ensuring portion can be greatly deformed in the vertical direction. Therefore, the angle of the sole and the angle of the ankle of the shoe wearer will not bend excessively. Therefore, the shoeboard of the utility model and the sole including the shoeboard improve the balance stability performance.

[0098] Furthermore, when the shoe wearer walks or runs, the propulsion ensuring portion of the shoe plate bends upward in the ascending direction relative to the support body, and then elastically returns to its original shape at the moment when the front end of the sole leaves the ground, thereby accelerating the shoe wearer forward. Therefore, the shoe plate and the sole including the shoe plate of the utility model have improved propulsion performance to help the shoe wearer walk or run quickly with less energy.

[0099] Furthermore, in the shoe plate of the present invention, like the propulsion ensuring portion, when the shoe wearer walks or runs, the forefoot balance stabilizing portion also bends upward in the ascending direction relative to the support body, and then elastically returns to its original shape at the moment when the front end of the sole leaves the ground. Therefore, like the propulsion ensuring portion, the forefoot balance stabilizing portion can contribute to improving propulsion performance.

[0100] In addition, in the shoe plate including a pair of rear foot balance stabilization parts and an impact reduction part according to an exemplary embodiment of the utility model, the pair of rear foot balance stabilization parts can reduce the degree of ankle bending caused by unstable heel landing. Since the upper midsole part and the lower midsole part made of foam resin are in direct contact with each other through the impact reduction part, the impact during heel landing is significantly reduced. Therefore, the shoe plate of the utility model and the sole including the shoe plate have significantly improved cushioning performance and balance stability performance.
