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.

The present disclosure relates generally to traction devices for footwear. In some embodiments, cleats are provided that are operable to provide preexisting articles of footwear with enhanced grip, traction and performance. Certain embodiments of the present disclosure comprise a threaded male extension for interfacing with a preexisting shoe sole and at least one projecting gripping element for contacting or extending toward a ground surface.

An object of the present invention is to provide a sole of a baseball spike shoe that improves a ball speed in a pitching motion. A sole includes a plurality of first protrusions arranged in a forefoot region of a sole body. Each of the first protrusions is formed such that its longitudinal direction extends along a foot width direction in a bottom view. When the plurality of first protrusions are projected on a virtual projection plane as viewed from a front side of the sole body, the sum of projection lengths of the plurality of first protrusions in the foot width direction is 85% or more and 100% or less of a distance of a straight line connecting in the foot width direction a side of the most medial first protrusion to a side of the most lateral first protrusion.

An outer sole for a golf shoe includes a plurality of cleats distributed along a forefoot area and a heel area. The cleats are integrated with the outer sole and extend from a surface of the outer sole that faces away from the shoe. The plurality of cleats includes at least a larger sized set of cleats and a smaller sized set of cleats. Such outer sole for a golf shoe gives good traction on the golf course but is also useable as a casual shoe off the golf course.

An outsole for an athletic shoe that includes a heel section and a forefoot section. The heel and forefoot sections are on the outer surface of the outsole. The forefoot section includes a tread pattern that provides first and second ground friction forces. The first ground friction force promotes rotation in a first rotational direction about a rotation point of the forefoot section. The second ground friction force restricts rotation in a second rotational direction about the rotation point. The second rotational direction is opposite of the first rotational direction and the second ground friction force is greater than the first ground friction force.

An outsole for a shoe including first and second sole segments that overlap at least partially. The first sole segment can include at least one stud and be arranged at least in a mid-foot portion of the outsole. The second sole segment can include at least one stud and be arranged at least in a toe portion of the outsole. In some embodiments, the outsole can include a first cushion element arranged between the first sole segment and the second sole segment and overlapping with at least one first stud of the first or second sole segment. In some embodiments, the outsole can include a second cushion element being arranged between the first sole segment and the second sole segment and overlapping with at least one second stud of the first or second sole segment. In some embodiments, the outsole may be an outsole for a football shoe.

An article of footwear may include an outsole having an opening extending from a top face of the outsole to a ground-contacting face of the outsole, and a traction member disposed within the opening in the outsole. The traction member has a protruding portion and flange portion extending from an upper end of the protruding portion. The flange portion is secured to the top face of the outsole.
