Abstract: Provided is a shock absorber formed by a resin composition and provided in a shoe, the shock absorber satisfying all formulas (1) to (4) below when changes in storage elastic modulus between 20° C. to 50° C. are linearly approximated by a least-squares method: Y=aX+b . . . (1); ?0.1?a??0.02 . . . (2); 1.0?b?16.0 . . . (3); and R2?0.75 . . . (4), where X represents a temperature (unit: ° C.) of the shock absorber, Y represents a storage elastic modulus of the shock absorber, and R represents a correlation coefficient in the least-squares method.

Abstract: A plurality of rubber-made medial cleats project from a base surface of an outsole in a medial portion of a forefoot portion, and a plurality of rubber-made lateral cleats project from the base surface of the outsole in a lateral portion of the forefoot portion, wherein a first engaging surface of each of the medial cleats faces toward a posterior direction or an obliquely posterior direction and a second engaging surface of each of the lateral cleats faces toward an anterior direction or an obliquely anterior direction.

Abstract: A monolithic three-dimensional memory device includes a first alternating stack of first insulating layers and first electrically conductive layers located over a top surface of a substrate, an insulating cap layer overlying the first alternating stack, a second alternating stack of second insulating layers and second electrically conductive layers and overlying the insulating cap layer, memory openings extending through the second alternating stack, the insulating cap layer, and the first alternating stack, memory stack structures located within the memory openings, and annular spacers located within the insulating cap layer and laterally surrounding a respective one of the memory stack structures.

Abstract: A flexible member includes a reinforced area reinforced by first and second reinforcement portions, wherein: the area is defined by the posterior edge of a first reinforcement portion and the anterior edge of a second reinforcement portion; the first and second reinforcement portions are smoothly continuous with each other without gaps; the perimeter of the area is completely surrounded by the first and second reinforcement portions; the virtual first center line of the area extends obliquely forward and upward; and the angle formed between the first center line and the tread surface of the sole is about 40° to 55°.

Abstract: A shoe sole including: an outsole having a tread surface to be in contact with a road surface; and a midsole arranged on the outsole, wherein: the midsole is exposed in a central section of a rear foot section and an arch section; in the central section and a lateral side section of the rear foot section of the shoe sole, a diagonal groove is formed extending in a diagonal front-rear direction in the rear foot section to an outer edge of a lateral side of the rear foot section; an angle ?, formed between a virtual center line of the diagonal groove and a longitudinal axis connecting between a center of a heel and a middle point between a big-toe ball and a little-toe ball, is set in a range of 12° to 35°; and a virtual intersection point between the longitudinal axis and the center line is set within a range of 21% to 43% of a full length of the longitudinal axis of the shoe sole from a posterior end of the shoe sole, the diagonal groove extending to a point anterior and medial to the intersection point.
