Field of the Invention The present invention relates to a shoe provided with a sole having a step portion having a novel shape and structure, and more particularly to a shock absorbing, cushioning, stability and braking property of the step portion. The present invention relates to shoes which are excellent and are preferably used as sports shoes and the like.

である。2. Description of the Related Art When walking or exercising while wearing shoes, a considerable load or impact is applied to a stepped portion of a shoe sole. The step on the sole of the shoe is a portion where the shoe steps on the ground before walking off the ground during walking or running, and in terms of the skeleton, the heel and the finger as shown in FIGS. It is an area corresponding to the front part of the foot (part centering on the metatarsal) between the two parts.

伝わると、足の故障を引き起こす原因となる。[0003] Assuming that the load (weight only) when a person wears shoes and stands in a standing position is 1, the magnitude of the load applied to the tread portion of the shoe sole is about 1.3 when walking, and about 1.3 when jumping. In some cases, it is about three, and when a heavy exercise is performed in the front, rear, left and right directions, an even greater load and impact are applied to the stepped portion. Therefore, if the impact applied to the stepping portion is transmitted to the foot as it is, it may cause a failure of the foot.
【０００４】したがって、靴の設計を行う場合におい

のための形状面での工夫は特になされていない。[0005] On the other hand, no study has been made to absorb or reduce the impact applied to the tread portion by the shape of the tread portion of the shoe sole. That is, in the conventional stepping portion, the entire bottom surface is flat as shown in FIG. 9 (A), or the bottom surface is curved downward in an arc shape as shown in FIG. The shape is not particularly devised for absorbing and mitigating impact.

られて足の故障を引き起こす可能性があった。The tread portion having the conventional shape shown in FIGS. 9A and 9B is hardly deformed because there is no deforming element (a shape element for promoting deformation). Low absorbency. For this reason, conventionally, as described above, an attempt is made to absorb and mitigate the impact by the material of the stepped portion, but it is not possible to obtain satisfactory impact absorption and cushioning properties alone. Therefore, in a case where a strenuous exercise is performed while wearing a shoe having a conventionally shaped stepping portion, the impact applied to the stepping portion may be transmitted to the foot as it is, causing a foot failure.

る一因となったりしていた。A stepping portion having a central portion protruding downward as shown in FIG. 9B is unstable because both sides in the width direction of the bottom surface are not grounded, and the thumb is used when the footwork is left or right. When braking is performed by using the foot, the sole cannot be sufficiently gripped on the ground by the tread portion unless the shoe sole is greatly inclined. Therefore, the stepped portion having the shape shown in FIG. 9B is inferior in stability and braking performance, is one of the causes of sprains, and is one of the factors that hinders smooth footwork.

When the portion is formed, the concave portion becomes a deformable element and the stomping portion is easily deformed, and excellent shock absorption and cushioning properties are obtained.Also, on the bottom surface of the grounding portion located on both sides of the bottom surface of the shoe sole. The load concentrates and this part firmly touches the ground, which improves the stability and braking performance of the treading part, and in particular improves the grip of the grounding part, and improves the braking performance (left and right braking effect) on the left and right footwork It was found that it improved.

mm. Therefore, in the shoe of the present embodiment, in the cross-sectional shape of the tread portion at a cross section substantially perpendicular to the bottom surface of the shoe sole 30 and along the shoe width direction, the maximum depth of the tread portion is 1-3 mm. A recess 34 is formed,
Ground portions 36, 36 having a flat bottom surface are formed on both sides thereof.

The width of the grounding portions 36, 36 located on both sides of the concave portion 34 is made substantially equal to each other. In addition, no concave portion is formed on the front end side and the rear end side of the tread portion, and no grounding portion is formed on the rear end side. Therefore, in the shoe of the present embodiment, the grounding portions 36, 36
Are formed in a substantially inverted U-shape that is continuous on the front end side and separated at the rear end side of the stepped portion via the recess 34.

容易となる。According to the shoe of the present invention, the stepped portion of the shoe sole is easily deformed, and the stepped portion is excellent in shock absorption and cushioning properties. Further, since the load is concentrated on the bottom surface of the ground contact portion existing on both sides of the concave portion, the stability and braking performance of the tread portion are improved, and particularly, the braking performance for the left and right footwork is excellent. Therefore, according to the shoe of the present invention, it is possible to reduce the occurrence of a foot failure by reducing the impact applied to the stepping portion, and it is easy to perform smooth footwork.
