To get closer to. In such a case, since the first arch region is merely displaced so that the vertical space is relatively small, excessive stress concentration on each of the lower and upper upper portions is suppressed. For this reason, wrinkles and the like hardly occur in each of the lower and upper upper portions. As a result, the lower and upper upper portions can be easily fitted to the outer peripheral surface of the wearer's foot including the position of the inner vertical arch. In particular, the first arch covering portion of the lower upper portion located on the inner back side can be easily fitted to the inner vertical arch of the wearer's foot having a complicated curved shape from below. And it becomes possible to stably support the wearer's foot focusing on the inner vertical arch so as not to be shifted in the shoe by the lower upper portion and the upper upper portion.

  The third mode is characterized in that, in the second mode, the vertical interval of the first arch region is larger than the vertical interval of the first toe region.

  In the third embodiment, the adjustment amount for narrowing the vertical space between the first arch regions is relatively large. For this reason, it is possible to improve the fit and supportability of the wearer's foot with the emphasis on the inner vertical arch.

  In a fourth mode, in any one of the first to third modes, the upper is disposed at a position corresponding to the outer back side of the wearer's foot, and a vertical direction between the lower upper portion and the upper upper portion. It further has a second gap provided between them. The lower upper portion is disposed at a position corresponding to the outer side of the wearer's foot, and includes a second arch covering portion for laterally covering the outer vertical arch of the wearer's foot. The second gap includes a second arch area located at a position corresponding to the outer vertical arch of the wearer's foot. The tightening portion is configured so as to tighten the lower upper portion and the upper upper portion in the second gap portion, and to be able to adjust the interval so that the vertical interval of the second arch region is reduced. And

  In the fourth embodiment, when the vertical space between the second arch regions is reduced by the tightening portion, the outer peripheral surface of the wearer's foot includes the lower vertical portion and the upper upper portion each including the position of the outer vertical arch. To get closer to. In such a case, since the second arch region is merely displaced such that the vertical interval is relatively small, excessive stress concentration on each of the lower and upper upper portions on the outer shell side is suppressed. You. For this reason, wrinkles and the like hardly occur on the lower and upper upper portions on the outer shell side.

In this case, the wearer approaches the outer peripheral surface of the wearer's foot F (see FIG. 4). In such a case, since the first arch region 11b is merely displaced such that the vertical interval is relatively small, excessive stress concentration on each of the lower and upper upper portions 5, 10 is suppressed. You. For this reason, wrinkles are less likely to occur in each of the lower and upper upper portions 5, 10. As a result, the lower and upper upper portions 5, 10 can be easily fitted to the outer peripheral surface of the wearer's foot F including the position of the inner vertical arch MA. In particular, the first arch covering portion 7 of the lower upper portion 5 located on the inner back side can be easily fitted to the inner vertical arch MA of the wearer's foot F having a complicated curved shape from below. Then, it is possible to stably support the wearer's foot F focusing on the inner vertical arch MA so as not to be displaced in the shoe S by the lower upper portions 5, 5 and the upper upper portion 10. Therefore, in the shoes S, it is possible to improve the fit and support of the wearer with respect to the foot F with at least the inner vertical arch MA as an important point.

  Further, the tightening portion 20 is configured to be able to adjust each interval in the first toe area 11a and the first arch area 11b so that each interval in the vertical direction is reduced. For this reason, by narrowing the vertical interval in both the first toe region 11a and the first arch region 11b by the tightening portion 20, the lower and upper upper portions 5, 10 are moved from the toes to the inner vertical arch MA. It is easy to fit the outer peripheral surface of the wearer's foot F including the spanned portion. In addition, it is possible to stably support the portion of the wearer's foot F extending from the toe to the inner vertical arch MA so as not to be displaced in the shoe S by the lower upper portions 5, 5 and the upper upper portion 10. Become. Therefore, in the shoe S, the fit and support of the wearer with respect to the foot F, which emphasizes the toes and the inner vertical arch MA, can be improved.

  Further, the tightening portion 20 is configured so as to tighten the lower upper portion 5 and the upper upper portion 10 in the second gap portion 12 and to adjust the interval so that the vertical interval of the second arch region 12b is reduced. ing. In such a configuration, when the vertical interval of the second arch region 12b is reduced by the tightening portion 20, each of the lower and upper upper portions 5, 10 includes the foot of the wearer including the position of the outer vertical arch LA. F approaches the outer peripheral surface. In such a case, since the second arch region 12b is merely displaced so that the vertical interval is relatively small, excessive stress on each of the lower and upper upper portions 5, 10 on the outer shell side is obtained. Concentration is suppressed. For this reason, wrinkles and the like hardly occur on each of the lower and upper upper portions 5 and 10 on the outer shell side. As a result, the lower and upper upper portions 5, 10 can be easily fitted to the outer peripheral surface of the wearer's foot F on the outer shell side. In particular, the second arch covering portion 9 of the lower upper portion 5 located on the outer shell side is formed by a portion where a part of each bone constituting the outer vertical arch LA of the wearer's foot F projects toward the outer shell side. Is easily wrapped around from the side. Therefore, in the shoe S, the fit of the wearer to the foot F including the outer vertical arch LA can be improved.
