A footwear traction device configured to be disposed about footwear comprising an openwork traction base defining a first opening and a second opening,
- the first opening defined by a first polygonal form having at least four sides with each side having 1 to 4 cleats coupled thereto and relatively positioned such that the first opening is predominantly below a forefoot during use;
- the second opening defined by a second polygonal form having at least three sides and relatively positioned such that the second opening is predominantly below a midfoot and/or a hindfoot during use,
- the openwork traction base comprises at least three cleats and configured such that the at least three cleats are relatively positioned such that at least one of the at least three cleats is disposed predominantly below the hindfoot during use, and
- wherein the openwork traction base is a polymeric material with a hardness of Shore 80 A to Shore 98 A.
