Definitions
- the present invention relates to athletic shoes with improved fit of the upper
- fats are designed in consideration of the shape of the foot when stationary.
- the shape of the foot during exercise is constantly changing in the shoe. That is, during exercise, the sole may not be able to follow the deformation of the foot and the sole may separate from the foot, or conversely, the upper may restrain the natural deformation of the foot. Therefore, when the upper is taken as a part that allows the sole to follow the foot, it is desirable that the upper deforms following the change in the shape of the foot during exercise. Fitting is required for In order to improve the fit, it is desirable that the strain distribution of the upper part be close to the strain distribution of the foot.

- each stretchable portion 50, 51 is adapted to the strain of the foot.
- the direction in which each of the elastic portions 50 and 50 can extend and contract can be adjusted.
- the area may be covered from the inside with the rear part 4 of the upper U.
- Action of the outer elastic part is to protect the area corresponding to the scaphoid head of the foot and its vicinity.
- the outer elastic portion 50 is formed in a substantially rectangular shape, a substantially rectangular shape, or a substantially trapezoidal shape approximating a triangle.
- the portion corresponding to the fifth metatarsal distal head 90 or its vicinity is set to have a length in the foot length direction.
- a small expandable and contractible portion 500 having an inverted triangular shape is provided outside the foot.
- the expansion of the elastic portion 500 becomes flat as shown by the one-dot chain line M in FIG.
- the elongation percentage is zero at the bottom point 501 of the elastic portion 500. That is, since the inverted triangular elastic portion 500 does not have a fixed length in the foot length direction L in the lower portion, the lower portion hardly expands. Therefore, most of the outer side surface of the upper hardly extends in the foot length direction L.
- FIG. 15 (e) a small expandable and contractible portion 500 having an inverted triangular shape is provided outside the foot.
- the outer elastic portion 50 is formed in a substantially rectangular shape or a substantially rectangular shape.
- a connecting portion 69 that is difficult to expand and contract is provided between the outer elastic portion 50 and the sole S.
- the outer elastic portion 50 expands as shown by a two-dot chain line M ⁇ in the figure.
- the outer elastic portion 50 has a certain length in the foot length direction L. Can extend in direction L. That is, in the range from the portion 0 to the second opening 2, the outer elastic portion 50 can expand and contract back and forth, while in FIG.
- the outer elastic portion 50 has a substantially trapezoidal shape approximating a triangle. It is formed and provided from the second opening 1 to the upper surface of the sole S. In such a structure, the length of the outer elastic portion 50 near the second opening 2 is extremely short. However, the outer elastic portion 50 has a V-shaped or U-shaped notch 58 near the second opening 2. Therefore, even in such a structure, the outer elastic portion 50 can expand and contract in the foot length direction L near the second opening 2.
- the outer elastic portion 50 can be deformed into various shapes according to the external force. Therefore, during exercise, the outer elastic portion 50 expands in response to the deformation of the foot, and the anterior portion 3 and the posterior portion 4 move independently from each other with the boundary near the fifth metatarsal distal head 90 as a boundary. can do. As a result, the upper can follow different forefoot and hindfoot movements.
- the outer elastic portion 50 has elastic means that can expand and contract along the foot length direction L.
- the upper can easily and easily react to the movement of the forefoot and hindfoot greatly different from the outer elastic part 50. Can follow enough.
- the expansion / contraction means in the region including the region ⁇ can be embodied by the outer elastic portion 50 having a certain length in such a region.
- the outer elastic portion 50 When high elasticity is required like running shoes, the outer elastic portion 50 is provided so as to cross the outer surface of the upper U from the second opening 2 to the upper surface of the sole S. When appropriate elasticity and sufficient support are required, as in the case of court competition shoes and trail shoes, a connecting portion 69 is provided between the outer elastic portion 50 and the sole S. Alternatively, on the upper surface of the sole S, the outer elastic portion 50 may not have a length that can expand and contract.
- the expansion / contraction means in the vicinity of the second opening 2 can be embodied by the outer expansion / contraction portion 50 having a certain length along the first opening 2. Even in the case of the substantially triangular outer elastic portion 50 having the extremely short length, the outer elastic portion 50 has a U-shaped or V-shaped notch 58 near the second opening 2. If it does, it can be used as an expansion and contraction means.
- a member 59 which is difficult to expand and contract at the center of the outer elastic portion 50 may be provided in an island shape as shown in FIG. 15 (c). .
- the outer elastic portion 50 may be formed in a shape in which the outer elastic portion 50 is narrowed at the upper and lower centers.
- the elastic constant k per unit height W (Fig. 15 (a)) of the outer elastic portion 50 is 0.1 / mm ⁇ 50 It is preferable to set it to about N / mm.
- the elastic constant is obtained by cutting a test piece elongated in the foot length direction from the elastic part and applying a load f along the foot length direction to the test piece.
- the thickness of the material of the upper is not clear. That is, it is difficult to measure the exact thickness of the upper material. Therefore, it is difficult to obtain an accurate value of the following Young's modulus of the material of the upper.
- the "elastic constant" k can be obtained without measuring the exact thickness of the upper material.
- Young's modulus is defined as a value obtained by dividing the load f by the strain ⁇ of the test piece and the cross-sectional area S of the test piece. That is, Young's modulus E is expressed by the following equation (2).
- the preferred value of the elastic constant k varies depending on the use, size and type of the shoe, and the shape and size of the elastic portion.
- the elastic constant k is set to about 0.1 N / mm to 7.0 N / mm in the shoes shown in FIGS. 1 to 11 (b) and 14 (a) to 14 (c). Is preferred.
- the elastic constant k is, for example, as shown in FIGS.
- the elastic portion 50 must be formed to be somewhat longer in the foot length direction L. Therefore, if the elastic portion 50 is made too easy to stretch, the function of holding the foot will be too low. Therefore, the elastic constant k of the material of the elastic portion 50 is set to be large in accordance with the fact that the elastic portion 50 is formed longer in the foot length direction L.
- the present invention is used for various sports shoes such as running shoes, walking shoes, paralle poles, basket poles, tennis courts, etc., trail shoes such as mountain climbing, golf shoes, and shoes. be able to.
- sports shoes such as running shoes, walking shoes, paralle poles, basket poles, tennis courts, etc.
- trail shoes such as mountain climbing, golf shoes, and shoes.
- the present invention is applied to a golf shoe made of a hard resin sole, providing a bent groove in the sole corresponding to the position where the elastic member is provided improves the fit.
