A stud of an outsole structure includes: a tubular body having a ground contact portion that comes into contact with ground, and a hole passing through the stud upward from the ground contact portion; a core disposed inside the hole and extending vertically; and a plurality of partition walls disposed above the ground contact portion and extending radially from the core toward an inner wall surface of the tubular body. An outsole body has a plurality of locking portions disposed below the partition walls. Each of the locking portions is locked to an associated one of the partition walls in a state in which an upper end portion of the locking portion is in contact with a lower end portion of the associated partition wall.

Outsole structure, method for producing the same, and cleated shoe including outsole structure

A shoe upper of a shoe includes first and second shoe upper sections together surrounding a foot, while covering a tiptoe and a heel of the foot, and a protector provided on part of an outer surface of the second shoe upper section and made of a single type of abrasion resistant resin material. The protector includes a tiptoe protector arranged to correspond to a tiptoe portion of the second shoe upper section, and a medial region protector provided on a medial region, of the second shoe upper section, extending from a backend of the tiptoe protector to a portion of the midfoot. The medial region protector has a deformable portion which has a mesh structure and is more deformable than the tiptoe protector, and a plurality of reinforcement ribs which divide the deformable portion into a plurality of regions.

Shoe upper and shoe including the shoe upper

A simplified sole structure for a baseball spiked shoe can improve cushioning properties of a heel region of the sole structure and can enhance comfort when wearing the shoe. The baseball spiked shoe includes a first midsole of a soft elastic member that is disposed at a heel central portion of the shoe, a second midsole of a soft elastic member that is disposed around and outwardly e.g. horizontally away from the first midsole via a circumferential groove therebetween and that is integrated with or unitary as one unit with the first midsole, and an outsole plate of a hard elastic member that is disposed on lower surfaces of the first and second midsoles, that has a plurality of spikes fitted thereon, and that has a hardness greater than a respective hardness of each of the first and second midsoles.
