W. Prick or at −10° C. Prick; and
wherein the outsole includes a second material that is compatible for compression molding with the at least one element and is less hard and less dense than the at least one element.
2. The article of footwear according to claim 1 , wherein the second material of the outsole includes ethylene vinyl acetate with blowing agents.
3. The article of footwear according to claim 1 , wherein the second material of the outsole is selected from a group consisting of rubber, thermoplastic urethane, and ethylene vinyl acetate with blowing agents.
4. The article of footwear according to claim 1 , wherein the outsole comprises two materials selected from a group consisting of rubber, thermoplastic urethane, and ethylene vinyl acetate with blowing agents.
5. The article of footwear according to claim 1 , wherein the at least one element is outwardly visible on the sole.
6. The article of footwear according to claim 1 , wherein the at least one element comprises a plurality of elements and at least one of the plurality of elements is outwardly visible on the sole.
7. The article of footwear according to claim 1 , wherein the at least one element includes a foil layer that is outwardly visible on the sole.
8. The article of footwear according to claim 1 , wherein the at least one element includes an electroplated member that is outwardly visible on the sole.
9. The article of footwear according to claim 1 , wherein the at least one element provides torsional reinforcement for the sole.
