A traction element arrangement for a sole structure of an article of footwear is described. Traction elements of a first group are associated with a lateral side of the sole structure. Traction elements of a second group are associated with a medial side of the sole structure. Traction elements of the second group include medial rotational traction elements that have a plurality of stud elements arranged in a circular grouping. Stud elements may be aligned laterally across the sole structure with traction elements of the first group. Stud elements may be aligned longitudinally across the sole structure to be arranged in different configurations along an outside medial side or an inside medial side.

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.

A mid-sole traction device for a shoe or a boot comprises a traction platform formed of a flexible rubber material. The platform has a first face for contacting a ground surface and a second face for attachment to a mid-sole of the shoe/boot. The first face is spaced from the second face. First and second protrusions are formed on the first face. The first protrusion has first and second ends, each of which defines an opening for receiving a spike. The second protrusion has first and second ends, each of which defines an opening for receiving a spike. The second protrusion is separate and spaced from the first protrusion. A first slot is formed in the platform and is located near a first peripheral edge of the platform for receiving a strap. A second slot is formed in the platform near a second peripheral edge for receiving a strap.
