Abstract: 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.

Abstract: An upper for a shoe adapted to cover a foot of a shoe wearer includes a base fabric layer. The base fabric layer of the upper has a first upper material formed of natural leather and constituting a first upper area, and a second upper material formed of a material other than natural leather and constituting a second upper area. A surface material formed of resin film is fixedly attached on the base fabric layer. The surface material covers both the first and second upper materials so that an outer surface of the base fabric layer can be coated by one surface layer formed of the surface material.
