On the side receiving the sole, a recess having a size surrounding the entire periphery of the sole is formed, and a rising portion of the recess is used as a first layer side outer edge portion, and the sole peripheral edge inner region of the sole is formed. The first layer side foot receiving part is formed,

前記第一層側足受部の横幅は、足の前足部、中足部、後足部の各々の横幅に対応して増減されており、The width of the first layer side foot support portion is increased or decreased corresponding to the width of each of the front foot portion, middle foot portion, and rear foot portion of the foot,

前記第一層側外縁部は、The first layer side outer edge portion is
前記第一層側足受部側となる内壁が、前記各々の前記足裏における縁に略対応する曲面にされて前記足裏の縁を受けるようにされ、かつ外壁が前記足裏の縁を超える外側位置にされて、前記内壁と当該第一層の外壁とでなす横断面が略半山形状にされ、The inner wall on the side of the first layer side foot receiving part is formed into a curved surface substantially corresponding to the edge of each of the soles so as to receive the edge of the soles, and the outer wall covers the edge of the soles. The cross section formed by the inner wall and the outer wall of the first layer is formed in a substantially half-mountain shape at an outer position exceeding

前記略半山形状は、その横幅及び高さが前記各々に対応する領域に応じて増減されており、The substantially half-mountain shape is increased or decreased according to the area corresponding to each of the width and height thereof,

前記前足部に対応する領域は、その第一層側外縁部の高さが前記中足部、前記後足部の各々の領域よりも低くされ、その内壁の前記曲面が最も緩やかな傾斜にされ、In the region corresponding to the front foot, the height of the outer edge portion on the first layer side is lower than each region of the middle foot portion and the rear foot portion, and the curved surface of the inner wall is inclined most gently. ,

前記第二層は、The second layer is
前記全周囲の前記第一層側外縁部の頂の全てを覆って、かつ足の３アーチを形成させるための凸部を成型して前記第一層に積層されて前記第一層側外縁部上に形成された第二層側外縁部で前記足裏の縁を受けると共に、前記第一層側足受部の上に存在する第二層側足受部で前記足裏の足裏周縁内側領域を受けるThe first layer side outer edge portion is formed by covering the entire circumference of the first layer side outer edge portion and forming a convex portion for forming the three arches of the foot to be laminated on the first layer. The edge of the sole is received by the outer edge on the second layer side formed on the inner side of the sole periphery of the sole at the second layer side foot rest existing on the first layer side foot rest. Receive area
ようにされていることを要旨とする。The gist of this is

以下、本件発明の実施の形態について、添付図面を用いて説明する。なお、本件発明は、これら実施形態に何ら限定されるべきものではなく、その要旨を逸脱しない範囲において、種々なる態様で実施し得る。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Incidentally, the present invention is not in any way be limited to these embodiments without departing from the scope and spirit thereof, that obtained worked in various aspects.

また、「足裏の央部」とは、「足裏の周縁部」のその内側の部分のことをいう（足裏周縁部内側部分ともいう）。つまり、「足裏の央部に対応する足受部」とは、足裏の周縁部のその内側でのインソールの部分のことである。「足裏の央部に対応する足受部」は足裏が直接に接するインソールの領域であるともいえる。ただし、土ふまずに対応する領域などもこの足受部に含まれる。 Further, the "foot central portion of the back" (also referred to as a sole periphery inner portion) which refers to the inner part of the "leg peripheral portion of the back." In other words, the “foot receiving portion corresponding to the central portion of the sole” refers to a portion of the insole inside the peripheral portion of the sole. It can be said that the “foot support portion corresponding to the center of the sole” is an insole region where the sole directly contacts. However, an area corresponding to a soil arch is also included in this footrest.
