Abstract: A midsole includes an upper layer and a lower layer made of a foamed material; the upper layer is a low-hardness foamed material; the lower layer is a high-hardness foamed material; the low-hardness foamed material of the upper layer is a low-hardness, high-resilience material that has a higher specific gravity than the high-hardness foamed material, that has a low hardness that is lower than the hardness of the high-hardness foamed material, and that has a higher speed at which to recover to an original shape after being deformed than that of the high-hardness foamed material.

Abstract: A shoe sole which has a landing surface composed of three regions of a middle-sole region, a fore-sole region and a rear-sole region, and has a plurality of groove portions in the landing surface. The groove portions include: a first groove portion located in the fore-sole region, on a first imaginary line extending along the MP joint; a second groove portion located in the fore-sole region, on a second imaginary line extending along a line which connects a medial outer edge of the fore-sole region and a lateral outer edge of the middle-sole region with each other, in an area which is closer to a toe than to the first groove portion; and a third groove portion located in the rear-sole region, on a third imaginary line extending along a line which connects a medial outer edge of the rear-sole region and a lateral outer edge of the middle-sole region with each other.

Abstract: A shoe includes: an upper; a tightening tool disposed above an instep of a wearer and capable of applying, to the upper, tightening force for drawing portions and on the both sides in a foot width direction of the upper; and an arch support part provided such that tightening force applied to a first side portion in a foot width direction of the upper can be transmitted to the arch support part. The tightening force transmitter has stretchability in foot girth directions set higher than that of the arch support part.

Abstract: A shoe sole 1 includes a bottom part 20 and a deformation restraining part 30. The bottom part 20 includes: a rear bottom surface part 24 formed to extend from a rearfoot to a midfoot portion and to be, when the shoe sole is placed on a virtual surface S as a flat surface, in contact with the virtual surface S; and a toe portion 26 of which a height from the virtual surface S is set to 100% or greater and 250% or less with respect to a thickness in the rear bottom surface part 24. The deformation restraining part 30 is disposed in an edge part on a medial side and a lateral side of the bottom part 20 and extends from a forefoot to the midfoot portion along the bottom part 20. The deformation restraining part 30 has higher hardness than the bottom part 20.

Abstract: A shoe sole includes a rear bottom surface part and a toe portion. The rear bottom surface part is formed to extend from a rearfoot portion to a midfoot portion and, when the shoe sole is placed on a flat virtual surface, the rear bottom surface part is in contact with the virtual surface. A height of the toe portion from the virtual surface is set to 170% or greater and 250% or less with respect to a thickness dimension in the rear bottom surface part.

Abstract: The present invention provides a shoe having a simpler structure compared to patent document JP-A 2010-162318, with reduced discomfort and enhanced repulsive force.
According to an aspect of certain embodiments of the present invention, a shoe 10 comprising: a middle sole 14 having a foot contacting surface 40 and a ground contacting surface 42; an upper at least partially covering the foot contacting surface 40 of the middle sole 14; and an elastic structure 18 curving upwards towards the rear direction at least from the outer foot side of the ground contacting surface is provided. With such configuration, discomfort can be reduced and repulsive force can be enhanced.

Abstract: A reinforcement structure is disposed on a midsole of a shoe. A first bar extends from a first point in a medial side of the midsole to a second point in the medial side of the midsole. The second point is closer to a toe of the shoe than the first point. A second bar extends from a third point in the medial side of the midsole to a fourth point in a lateral side of the midsole. The fourth point being closer to the toe of the shoe than the third point. A third bar extending from a fifth point in the medial side of the midsole to a sixth point in the lateral side of the midsole. The sixth point being closer to the toe of the shoe than the fifth point. The third bar extending further toward the toe of the shoe than the second bar.
