Description

  The present invention relates to a shoe sole having a heel and footwear including the shoe sole.

  BACKGROUND ART Conventionally, footwear having heels, such as heel shoes, heel sandals, and pumps, has a shape inclined upward from the toe side to the heel side, and the sole of the shoe has only the front bottom surface and the heel bottom surface grounded. Therefore, it is more unstable than general sneakers and flat shoes.

  On the other hand, in order to stabilize footwear having a heel, the following shoe sole has been proposed (for example, refer to Patent Document 1). This sole is a middle part in the length direction that extends from the toe side to the heel side of the shoe sole, where the heel side part is branched into an upper heel part and a lower heel part, and the bottom surface of the lower heel part is the toe side bottom surface. The upper heel part is inclined upward from the toe side at a required angle, and in the space between the bottom surface of the upper heel part and the upper surface of the lower heel part, from the branched position of the upper and lower heel parts to the tip of the heel side. A bridge connecting the bottom surface of the upper heel portion and the top surface of the lower heel portion is provided at the center of the foot width direction up to the required position (see FIGS. 2 and 6 of Patent Document 1).

  However, although the shoe sole of Patent Document 1 may improve stability on landing as compared with footwear having a conventional heel, since the overall shape is significantly different from footwear having a conventional heel, There is a problem that it is difficult to appeal to many consumers who want footwear having conventional heels.

  In addition, the shoe sole of Patent Document 1 has no heel or has a curved heel, and thus has a problem that the heel portion is weaker than conventional footwear having a heel.

  The present invention has been made in view of the above problems, and has a aesthetic appearance that is relatively close to the shape of footwear having a conventional heel, and considering the strength of the heel part as well, a shoe sole that is more stable than before and its An object is to provide footwear having a sole.

  A shoe sole according to one aspect of the present invention is a shoe sole having a heel, comprising a heel and a sole body extending along a bottom surface of an upper from a toe to the heel, The main body includes a front portion of the main body having a ground surface, a rear portion of the main body that inclines upward from the front portion of the main body to the heel, a rising portion that inclines upward, and a main body protruding portion that projects downward and the bottom surface is grounded. Have.

According to this structure, since the main body protrusion is provided and the bottom surface of the main body protrusion is grounded, the ground contact surface is increased and is more stable than the shoe sole of the conventional footwear having a heel. Further, since the main body protruding portion is arranged at the rising portion that is inclined upward, it has an aesthetic appearance relatively close to the shape of the shoe sole of the footwear having the conventional heel. Further, since the heel is provided, the strength of the heel portion is sufficient.

  Here, when a person walks, the ground starts from the outer rear side of the heel part, and after the whole sole contacts the ground, the sole separates from the front inner side of the toe part as a fulcrum. Therefore, the conventional shoe sole often wears away from the rear outer side of the heel portion, for example, the rear outer side of the heel. In addition, when a part of the sole wears out by a predetermined amount, it is necessary to replace the sole.

  Preferably, in the shoe sole, the center of the heel in the width direction of the bottom surface of the footwear is more outside than the centerline of the upper surface in the width direction in a rear view.

  Here, the rear view of the footwear refers to a state in which the footwear is viewed from the rear of the heel. According to this structure, the bottom surface of the heel is offset to the outside, which is stable and easy to walk. Further, it is possible to suppress the abrasion on the outer rear side of the heel.

  Preferably, in the shoe sole, the shoe sole body is integrally formed with the body front portion, the body rear portion, and the body protrusion portion, and the bottom surface of the body protrusion portion is the body front portion. It continues to the bottom.

  According to this configuration, since the sole body is integrally formed, it is easy to manufacture, and the strength is higher than that in the case where the front portion of the main body, the rear portion of the main body, and the protruding portion of the main body are formed separately. Get higher Further, since the bottom surface of the main body protrusion continues to the bottom surface of the front part of the main body, the stability is further increased.

  Preferably, in this shoe sole, the main material of the shoe sole body is an elastic material, and in the heel, the main material is a resin material or wood, and the elastic material is attached to the bottom surface.

  According to this configuration, since the main material of the shoe sole body is the elastic material, the shock during walking is absorbed. In addition, since the main material of the heel is resin or wood, it is possible to obtain sufficient strength in the heel part where the load is applied, and since the elastic material is attached to the bottom surface of the heel, this allows for impact during walking. Is also absorbed. Further, the elastic material on the bottom surface of the heel can be replaced, and maintenance is facilitated.

  Footwear according to an aspect of the present invention includes the shoe sole according to any one of claims 1 to 3. According to this structure, the footwear is stable with a shape close to that of the footwear having the conventional heel.

  Preferably, in the footwear, a part of the rear portion of the main body is partially interposed between the upper and the heel. According to this configuration, the upper and the heel are firmly attached, and further, since a part of the rear portion of the main body is partially interposed therebetween, the shoe sole main body is also firmly attached. As a result, the upper, the heel, and the sole body are firmly attached, and the heel and the sole body are prevented from coming off.

  According to the shoe sole and the footwear including the shoe sole of the present invention, the shoe sole and footwear more stable than ever can be obtained.
