Description

本発明は、靴底のアウトソールとミッドソールにおいて、それぞれトウ部の位置する前底がヒール部の位置する後底に比べて長手方向に斜め上向きに傾斜した傾斜部が形成されている構造の機能性履物であって、歩行時に身体のバランスが取れて安定的に着地でき、且つ、歩行者が足に力を入れなくてもミッドソールの傾斜角による自然な体重の移動により歩行が容易であり、歩行者の下半身の筋肉を発達させて運動量を増大させるとともに持久力、推進力と敏捷性などを高められる機能性履物に関する。 The present invention has a structure in which an outsole and a midsole of a shoe sole are each formed with an inclined portion in which the front sole where the toe portion is located is inclined obliquely upward in the longitudinal direction compared to the rear sole where the heel portion is located. It is a functional footwear that balances the body when walking and can land stably, and even if the pedestrian does not apply force to the foot, it is easy to walk due to natural weight shift due to the inclination angle of the midsole It relates to functional footwear that develops the muscles of the lower body of the pedestrian to increase the amount of exercise and increase endurance, propulsion and agility.

最近、大変人気を集めている、マサイ族の歩き方を参考にしたシューズは足の疲労感を低減できるようにした構造の機能性ウォーキングシューズであって、大韓民国登録特許第１０−８０００６０号公報、大韓民国登録特許第１０−７８６５５６号公報、大韓民国登録特許第１０−８００００６１号などに公知されているように、多種多様な構造の機能性ウォーキングシューズが登録されている。従来技術によれば、図１に示すように、これらの機能性ウォーキングシューズは前底のトウ部が位置する部分の高さと後底のヒール部が位置する部分の高さとがそれぞれアウトソール底面の中心部に比べてそれぞれｈ１、ｈ２に見合う分だけ高く形成されている構造になっている。ところが、かような従来のマサイ族の歩き方を参考にした機能性シューズは、普段平地を履いて歩行するに際してはあまり問題がないとはいえ、傾斜面や階段などを登ったり降りたりするときにはアウトソール底面の中心部の着地点が不安であるため身体のバランスを取り難く足に力が入ってしまう結果足が疲労し易く、しかも、次の歩幅のための事前動作が不安定になるなどの問題点があった。
一方、本発明者は、歩行時における足の疲労感を減らすために、大韓民国登録特許登録番号第１０−５３３５７５号をもって、図２に示すように、ミッドソール１００が水平に形成されているヒール部と水平に形成されるトウ部と、前記ヒール部から前記トウ部まで緩やかに斜め上向きに傾斜した傾斜部とからなる機能性履物に対して特許登録を受けている。しかしながら、従来技術によると、上記の如き機能性履物の場合にはトウキャップ２００の高さが高くて歩行時にはトウキャップが地面に頻繁にぶつかってしまうため自然な歩行ができないといった問題点があった。
従って、本発明者は、上記の如き問題点を解消するための方案として、履物のアウトソールとミッドソールの構造を同時に改善し、トウキャップを低めた機能性履物を製造することにより、上記の如き問題点を改善して本発明を完成するに至った。 Recently, the shoes based on the way of walking of the Maasai people, which are very popular, are functional walking shoes with a structure that can reduce the feeling of fatigue of the foot, and the Korean Patent No. 10-800060, Functional walking shoes having a wide variety of structures are registered, as known in Korean Patent Registration No. 10-786556, Korean Patent Registration No. 10-8000061, and the like. According to the prior art, as shown in FIG. 1, these functional walking shoes have a height of a portion where the toe portion of the front bottom is located and a height of a portion where the heel portion of the rear bottom is located on the bottom surface of the outsole. The structure is formed so as to be higher than the center portion by an amount corresponding to h 1 and h 2 . However, functional shoes based on the traditional Maasai way of walking are usually not a problem when walking on the flat ground, but when climbing up and down slopes and stairs etc. As the landing point at the center of the bottom of the outsole is uneasy, it is difficult to balance the body and force is applied to the foot. As a result, the foot is likely to get tired, and the preliminary movement for the next step becomes unstable. There was a problem.
On the other hand, in order to reduce the feeling of foot fatigue during walking, the present inventor has a Korean registered patent registration number No. 10-533575 and a heel portion in which the midsole 100 is formed horizontally as shown in FIG. Patent application has been received for a functional footwear comprising a toe part formed horizontally and an inclined part gently inclined upward from the heel part to the toe part. However, according to the prior art, in the case of the above functional footwear, the height of the toe cap 200 is high, and the toe cap frequently hits the ground during walking, so that there is a problem that natural walking is not possible. .
Accordingly, the present inventor has improved the structure of the outsole and the midsole of the footwear at the same time as a method for solving the above-mentioned problems, and manufactured the functional footwear with a lowered toe cap. The present invention was completed by improving such problems.

本発明は、従来技術における上記の問題点を解決するためになされたものであり、靴底のアウトソールとミッドソールにおいて、それぞれトウ部の位置する前底がヒール部の位置する後底に比べて長手方向に斜め上向きに傾斜した傾斜部が形成されている構造の機能性履物であって、歩行時に身体のバランスが取れて安定的に着地でき、且つ、歩行者が足に力を入れなくてもミッドソールの傾斜角による自然な体重の移動により歩行が容易であり、歩行者の下半身の筋肉を発達させて運動量を増大させるとともに持久力、推進力と敏捷性などを高められる機能性履物を提供するところにその目的がある。 The present invention has been made to solve the above-mentioned problems in the prior art, and in the outsole and midsole of the shoe sole, the front sole where the toe portion is located is compared with the rear sole where the heel portion is located, respectively. Functional footwear with a slanted portion that is inclined obliquely upward in the longitudinal direction, can balance the body during walking, can land stably, and pedestrians do not apply force to the feet However, functional footwear that is easy to walk due to natural weight shift due to the inclination angle of the midsole, develops the lower body muscles of the pedestrian, increases momentum and increases endurance, propulsion and agility etc. The purpose is to provide

上記の課題を解消するために、本発明は、靴底と甲革とからなる履物において、前記靴底のアウトソールとミッドソールはそれぞれトウ部の位置する前底がヒール部の位置する後底に比べて長手方向に斜め上向きに傾斜した傾斜部が形成されている構造のものであることを特徴とする機能性履物を提供する。
但し、前記アウトソールは、後底から前底まで長手方向に斜め上向きに傾斜した真っ直ぐな傾斜部が形成される構造のものであることを特徴とし、前記ミッドソールは、ヒール部からトウ部まで長手方向に緩やかに斜め上向きに傾斜した真っ直ぐな傾斜部が形成されている構造のものであることを特徴とする。 In order to solve the above problems, the present invention provides footwear comprising a shoe sole and an upper, wherein the outsole and midsole of the shoe sole each have a rear sole in which the front sole where the toe portion is located and the heel portion is located. The functional footwear is characterized by having a structure in which an inclined portion inclined obliquely upward in the longitudinal direction is formed.
However, the outsole has a structure in which a straight inclined part inclined obliquely upward in the longitudinal direction is formed from the rear bottom to the front bottom, and the midsole is formed from the heel part to the toe part. The present invention is characterized in that it has a structure in which a straight inclined portion that is inclined obliquely upward in the longitudinal direction is formed.

上記の課題解決手段による本発明は、靴底のアウトソールとミッドソールはそれぞれトウ部の位置する前底がヒール部の位置する後底に比べて長手方向に斜め上向きに傾斜した傾斜部が形成されている構造の機能性履物に関するものであり、歩行時に身体のバランスが取れて安定的に着地でき、且つ、歩行者が足に力を入れなくてもミッドソールの傾斜角による自然な体重の移動により歩行が容易であり、歩行者の下半身の筋肉を発達させて運動量を増大させるとともに持久力、推進力と敏捷性などを高められるという効果がある。 In the present invention according to the above problem solving means, the outsole and midsole of the shoe sole are each formed with an inclined portion in which the front sole where the toe portion is located is inclined obliquely upward in the longitudinal direction compared to the rear sole where the heel portion is located. It is related to the functional footwear of the structure that is able to balance the body when walking and can land stably, and even if the pedestrian does not put force on the foot, It is easy to walk by moving, and has the effect of developing the lower body muscles of the pedestrian to increase the amount of exercise and enhancing endurance, propulsion and agility.

本発明は上記事情に鑑みてなされたものであり、靴底と甲革とからなる履物において、前記靴底のアウトソールとミッドソールはそれぞれトウ部の位置する前底がヒール部の位置する後底に比べて長手方向に斜め上向きに傾斜した傾斜部が形成されている構造のものであることを特徴とする機能性履物に関するものである。
本発明に係る機能性履物は、後底の底面が水平に形成されていることから、歩行時に身体のバランスが取れて安定的に着地でき、且つ、歩行者が足に力を入れなくてもミッドソールの傾斜角による自然な体重の移動により歩行が容易であり、歩行者の下半身の筋肉を発達させて運動量を増大させるとともに持久力、推進力と敏捷性などを高められるという特徴がある。
本発明における「前底」と「後底」について、前底と後底が連結されていることを前提として定義する。すなわち、上向き傾斜部が始まる個所を境界面として、この境界面の前部のトウ部が位置する部分の底を前底ＯＦＬといい、ヒール部が位置する部分の底を後底ＯＢＬという。なお、上記において、トウ部とは、靴底における足指の接触部分のことをいい、ヒール部とは、靴底におけるかかとの接触部分のことをいう。
また、本発明においては、添付図面中において、便宜上、ミッドソールを中心としてトウ部とヒール部を具体的に示して符号を付しているが、アウトソールの場合にも前記ミッドソールと対応する位置の部分がそれぞれトウ部とヒール部であるとしてこの明細書を記述している。
さらに、本発明において、身体の足指部は趾骨と対応する足底部位を指し示し、身体の土踏まず部は中足骨と対応する足底部位を指し示し、身体のかかと部は足根骨と対応する足底部位を指し示すものとする。なお、トウ部は前記足指部が置かれる靴底の上面部分をいい、傾斜部は前記土踏まず部が置かれる靴底の上面部分をいい、ヒール部は前記かかと部が置かれる靴底の上面部分をいう。
以下、添付図面に基づき、本発明に係る機能性履物の構成を詳述する。
添付の各図面はこの分野における通常の知識を持った者が通常的に理解可能な構成要素については図示を省略あるいは簡略化して表示し、本発明と関連する構成要素を中心に示している。特に、構成要素間のサイズ比がやや異なるように表現される部分もあるが、このような図面の相違点はこの分野における通常の知識を持った者が容易に理解可能な部分であるため別途の説明は省略する。
本発明において、図３は本発明に係る機能性履物の技術的思想を説明するための履物の側面図であり、図４は本発明の好適な実施形態による機能性履物のアウトソールとミッドソールを長手方向に切断した断面を示す断面図であり、図５は本発明の好適な実施形態による機能性履物のミッドソールを示す斜視図である。
本発明に係る機能性履物は、着用者が歩行するときに地面に着地される底面と着用者の足底が置かれる上面とからなる靴底と、前記靴底と結合され、着用者の足指、かかと、足の甲及び足首を全体的に覆う甲革と、を有する通常の履物において、前記靴底のアウトソール１０とミッドソール２０はそれぞれトウ部の位置する前底がヒール部の位置する後底に比べて長手方向に斜め上向きに傾斜した傾斜部が形成される構造のものであることを特徴とする。
このため、上記の構造を有する機能性履物は後底の底面が水平に形成されることにより、従来のマサイ族の歩き方を参考にしたシューズに比べて安定的に着地可能であることから、傾斜した地面や階段などを歩行するときであっても何ら不便さを感じることなく安定的に歩行することができ、平地における歩行時には歩行者が足に力を入れなくてもミッドソールの傾斜角による自然な体重の移動により歩行が容易であるという特徴がある。
以下、添付図面に基づき、本発明における前記アウトソールの構造を詳述する。
本発明に係るアウトソール１０は、後底ＯＢＬから前底ＯＦＬまで長手方向に斜め上向きに傾斜した真っ直ぐな傾斜部が形成される構造のものであり、後底ＯＢＬの長さ対前底ＯＦＬの長さが５３〜５６対４４〜４７である個所において傾斜部が形成され、傾斜部はその傾斜角αが１３〜１７°の上向き構造であることが好ましい。本発明においては、前底ＯＦＬの全長が傾斜部を形成している。
上記において、傾斜部の形成個所と傾斜角の大きさは人体工学的に設計されており、傾斜部の形成個所が上記において限定した範囲よりも前部に形成されたり、あるいは、傾斜角が小さな場合には歩行に際して着地時に身体のバランスが取れて安定的であるが、歩行時に前底の傾斜角が小さくて自然な弾力動作が正常に行われないため足に多くの力が入ってしまい、且つ、傾斜部の形成個所が上記において限定した範囲よりも後部に形成されたり、あるいは、傾斜角が大きな場合には前底の傾斜角が大きくて次回の足取りをするための事前動作のために足に多くの力が入ってしまい、さらに、歩行に際して着地点に着地時に身体のバランスが崩れてしまって歩行者が疲労感を感じてしまう。
以下、添付図面に基づき、本発明における前記ミッドソールの構造を詳述する。
本発明に係るミッドソール２０は、本発明が大韓民国登録特許登録番号第１０−５３３５７５号をもって既に特許登録を受けている機能性履物のミッドソール構造を改良して採択したところに特徴があり、着用時に歩行者にできる限り疲労感を感じさせないように設計されている。
このため、本発明に係るミッドソール２０は、ヒール部２３からトウ部２１まで長手方向に緩やかに斜め上向きに傾斜した真っ直ぐな傾斜部が形成される構造のものであり、前記ミッドソールは、トウ部ＭＴＬの長さ対ミッドソールの全長ＭＬが０．２〜０．３対１であることが好ましい。トウ部の長さが０．２未満である場合には着用者の土踏まず部がトウ部２１から傾斜部２２にかけて置かれるため着用感が低下され、０．３を超える場合には着用者の足指部がトウ部２１から傾斜部２２にかけて置かれるため着用感が低下するという問題点が発生する恐れがある。
また、ヒール部２３の長さＭＨＬ対ミッドソールの全長ＭＬが０．１５〜０．２１対１の割合になるように形成することが好ましい。ヒール部２３の長さＭＨＬが０．１５未満である場合には人体の足をなす骨格のうち足根骨に相当する部分であるかかとの全体が前記ヒール部２３に当たらず、傾斜部２２からヒール部２３にかけて当たるため着用感に劣るという問題があり、０．２１を超える場合には着用者の土踏まず部が傾斜部２２からヒール部２３にかけて置かれるため着用感が低下するという問題点が発生する恐れがある。
そして、前記ミッドソール２０は、ヒール部２３からトウ部２１への傾斜度βが２．５〜４．０°の緩傾斜の真っ直ぐな上向き斜めの傾斜構造を形成することにより、歩行時にかかとが滑ることなく足指部が自然に置かれることにより着用感が向上され、歩行および運動をするのに適した傾斜度を有していて長時間に亘って歩行、運動などをしてもアキレス鍵に無理がなく効果的に運動量を増大させることができるという特徴を有する。
前記傾斜部２２の傾斜度βが２．５°未満である場合にはアキレス鍵の弛緩の度合いがあまり高くなくて運動量が少ないため普段簡単な運動により効果的に運動量を増やそうとする現代人の欲求を満たすことができないという問題があり、４．０°を超える場合にはアキレス鍵の弛緩の度合いが高いため運動量が大幅に増大するというメリットはあるが、着用感が低下してバランスを崩して倒れる恐れがあり、且つ、アキレス鍵に無理を与えるという問題点が発生する恐れがある。
本発明において、前記アウトソール１０とミッドソール２０に使用する素材は、通常的に、履物用アウトソールとミッドソールに使用する素材であって、ポリウレタン（ＰＵ）またはＥＶＡ発泡体であることが好ましく、上記において限定した発泡体素材に加えて、同等以上の物性を有する発泡体素材である場合にはその素材の種類を問わずに使用可能である。
このため、上記の構造を有する機能性履物は靴底のアウトソール１０とミッドソール２０が両方ともトウ部がヒール部に比べて緩やかに上向き斜めに傾斜した構造を有することにより、歩行時に身体のバランスが取れて安定的に着地でき、且つ、ミッドソールの傾斜角による自然な体重の移動により歩行が容易であり、歩行者の下半身の筋肉を発達させて運動量を増大させるとともに持久力、推進力と敏捷性などを高められる。
以上述べたように、本発明は添付図面を中心として本発明の優秀性を説明してきたが、本発明は必ずしも添付図面により限定されるものではなく、本発明の技術的思想を逸脱しない範囲内で種々の置換、変形及び変更が可能である。
上記の課題を解決するための本発明は、靴底と甲革とからなる履物において、前記靴底はアウトソールとミッドソールにおいてそれぞれトウ部の位置する前底がヒール部の位置する後底に比べて長手方向に斜め上向きに傾斜した傾斜部が形成される構造であることを特徴とする機能性履物を提供する。
但し、前記アウトソールは、後底から前底まで長手方向に斜め上向きに傾斜した真っ直ぐな傾斜部が形成される構造のものであることを特徴とし、前記ミッドソールは、ヒール部からトウ部まで長手方向に緩やかに斜め上向きに傾斜した真っ直ぐな傾斜部が形成されている構造のものであることを特徴とする。 The present invention has been made in view of the above circumstances, and in the footwear comprising a shoe sole and an upper, the outsole and the midsole of the shoe sole are respectively located after the front sole where the toe portion is located and the heel portion is located. The present invention relates to a functional footwear having a structure in which an inclined portion inclined obliquely upward in the longitudinal direction as compared with the bottom is formed.
In the functional footwear according to the present invention, the bottom surface of the rear bottom is formed horizontally, so that the body can be balanced and stably landed during walking, and the pedestrian does not need to apply force to the foot. It is easy to walk due to the natural movement of body weight due to the inclination angle of the midsole, and it is characterized by developing the lower body muscles of the pedestrian to increase the amount of exercise and enhancing endurance, propulsion and agility.
The “front bottom” and “rear bottom” in the present invention are defined on the assumption that the front bottom and the rear bottom are connected. That is, a portion where the upward inclined portion starts is defined as a boundary surface, the bottom of the portion where the front toe portion of the boundary surface is located is referred to as the front bottom OFL, and the bottom of the portion where the heel portion is located is referred to as the rear bottom OBL. In the above description, the toe portion refers to the contact portion of the toes on the shoe sole, and the heel portion refers to the contact portion of the heel on the shoe sole.
In the present invention, in the accompanying drawings, for convenience, the toe portion and the heel portion are specifically shown and labeled with the midsole as a center, but the case of the outsole also corresponds to the midsole. This specification describes the position portion as the toe portion and the heel portion, respectively.
Further, in the present invention, the toe portion of the body indicates a plantar region corresponding to the rib, the arch portion of the body indicates the plantar region corresponding to the metatarsal bone, and the heel portion of the body corresponds to the tarsal bone. Point to the plantar part. The toe portion refers to the upper surface portion of the shoe sole on which the toe portion is placed, the inclined portion refers to the upper surface portion of the shoe sole on which the arch portion is placed, and the heel portion refers to the upper surface portion of the shoe sole on which the heel portion is placed. Say part.
Hereinafter, based on an accompanying drawing, the composition of the functional footwear concerning the present invention is explained in full detail.
In the accompanying drawings, components that can be normally understood by those having ordinary knowledge in this field are shown by omitting or simplifying the drawings, and mainly show components related to the present invention. In particular, there are parts that are expressed so that the size ratios between the components are slightly different, but such differences in the drawings are parts that can be easily understood by those having ordinary knowledge in this field. Description of is omitted.
In the present invention, FIG. 3 is a side view of the footwear for explaining the technical idea of the functional footwear according to the present invention, and FIG. 4 is an outsole and midsole of the functional footwear according to a preferred embodiment of the present invention. FIG. 5 is a perspective view showing a midsole of a functional footwear according to a preferred embodiment of the present invention.
The functional footwear according to the present invention is combined with a shoe sole including a bottom surface that is landed on the ground when the wearer walks and an upper surface on which the wearer's sole is placed, and the shoe sole. In a normal footwear having a finger, a heel, and an upper covering the entire instep and ankle, the outsole 10 and the midsole 20 of the shoe sole are respectively positioned at the heel portion at the front sole where the toe portion is located. It is characterized by having a structure in which an inclined portion inclined obliquely upward in the longitudinal direction as compared with the rear bottom is formed.
For this reason, the functional footwear having the above structure can be stably landed compared to conventional shoes based on the Masai way of walking by forming the bottom of the back bottom horizontally. Even when walking on sloping ground or stairs, it is possible to walk stably without feeling any inconvenience. It is characterized by easy walking due to the natural movement of weight.
Hereinafter, the structure of the outsole according to the present invention will be described in detail with reference to the accompanying drawings.
The outsole 10 according to the present invention has a structure in which a straight inclined portion that is inclined obliquely upward in the longitudinal direction from the rear bottom OBL to the front bottom OFL is formed. It is preferable that an inclined portion is formed at a position where the length is 53 to 56 to 44 to 47, and the inclined portion has an upward structure with an inclination angle α of 13 to 17 °. In the present invention, the entire length of the front bottom OFL forms an inclined portion.
In the above, the formation part of the inclined part and the size of the inclination angle are designed ergonomically, and the formation part of the inclined part is formed in front of the range limited in the above, or the inclination angle is small. When walking, the body is balanced and stable when landing, but when walking, the inclination angle of the front sole is small and natural elastic movement is not performed normally, so a lot of force enters the foot, In addition, if the inclined portion is formed at the rear part of the range limited in the above, or if the inclination angle is large, the inclination angle of the front bottom is large, so that the preliminary operation for the next step is taken. A lot of force is applied to the feet, and the body balance is lost when landing at the landing point during walking, and the pedestrian feels tired.
Hereinafter, the structure of the midsole according to the present invention will be described in detail with reference to the accompanying drawings.
The midsole 20 according to the present invention is characterized in that the present invention has been adopted by improving the midsole structure of functional footwear which has already been patent-registered with the Korean Patent Registration No. 10-533575. Sometimes designed to keep pedestrians from feeling as tired as possible.
For this reason, the midsole 20 according to the present invention has a structure in which a straight inclined portion that is gently inclined obliquely upward in the longitudinal direction from the heel portion 23 to the toe portion 21 is formed. It is preferable that the length of the part MTL to the total length ML of the midsole is 0.2 to 0.3 to 1. When the length of the toe portion is less than 0.2, the wearer's arch portion is placed from the toe portion 21 to the inclined portion 22, so that the feeling of wear is reduced. Since the finger portion is placed from the toe portion 21 to the inclined portion 22, there is a possibility that a problem that the feeling of wear is lowered may occur.
Moreover, it is preferable to form so that the length MHL of the heel portion 23 and the total length ML of the midsole may be in a ratio of 0.15 to 0.21: 1. When the length MHL of the heel portion 23 is less than 0.15, the entire heel corresponding to the tarsal bone of the skeleton forming the foot of the human body does not hit the heel portion 23, but from the inclined portion 22. There is a problem that the wear feeling is inferior because it hits the heel part 23, and when it exceeds 0.21, the wearer's arch part is placed from the inclined part 22 to the heel part 23, so that the wear feeling is lowered. There is a fear.
The midsole 20 forms a straight upward slant structure having a gentle slope with a slope β from the heel part 23 to the toe part 21 of 2.5 to 4.0 °, so that the heel during walking is high. The toe part is naturally placed without slipping, so that the feeling of wear is improved, and it has a slope suitable for walking and exercising, and even if it walks and exercises for a long time, the Achilles key There is a feature that the momentum can be effectively increased without excessive force.
When the inclination β of the inclined portion 22 is less than 2.5 °, the degree of relaxation of the Achilles key is not so high and the amount of exercise is small, so that a modern person who wants to increase the amount of exercise effectively by simple exercise is usually used. There is a problem that the desire cannot be satisfied, and if it exceeds 4.0 °, the degree of relaxation of the Achilles key is high, so there is a merit that the momentum greatly increases, but the feeling of wearing decreases and the balance is lost. May fall, and there may be a problem that the Achilles key is forced.
In the present invention, the material used for the outsole 10 and the midsole 20 is generally a material used for the outsole and midsole for footwear, and is preferably polyurethane (PU) or EVA foam.

Balanced and stable landing, easy walking due to natural weight movement due to the inclination angle of the midsole, developing the muscles of the lower body of the pedestrian to increase the momentum and endurance, propulsion And agility can be improved.
As described above, the present invention has been described with respect to the superiority of the present invention centering on the attached drawings. However, the present invention is not necessarily limited by the attached drawings, and does not depart from the technical idea of the present invention. Various substitutions, modifications and changes are possible.
The present invention for solving the above-described problems is directed to footwear comprising a shoe sole and an upper, wherein the shoe sole is located on the outsole and midsole, with the front sole located at the toe portion being the rear sole located at the heel portion. A functional footwear characterized by having a structure in which an inclined portion inclined obliquely upward in the longitudinal direction is formed.
However, the outsole has a structure in which a straight inclined part inclined obliquely upward in the longitudinal direction is formed from the rear bottom to the front bottom, and the midsole is formed from the heel part to the toe part. The present invention is characterized in that it has a structure in which a straight inclined portion that is inclined obliquely upward in the longitudinal direction is formed.
