An article of footwear including an upper having an opening for receiving a wearer's foot, a insole for supporting the wearer's foot, and an outsole. The upper, the insole and the outsole are comprised of at least two different forms of injection molded polymer materials permanently bonded at interfaces between the different forms of polymer materials to provide an integrally formed and unitary article of footwear. For example, the upper is formed of a limb silicone material, the insole is formed of a silicone gel material, and the outsole is formed of a silicone foam material. The method for manufacturing the integrally formed injection molded article of footwear includes providing a mold having at least one cavity for forming the article of footwear and providing the at least two different forms of polymer materials. A controlled amount of each of said tat lest two different forms of polymer materials are injected into the mold cavity at a predetermined temperature and a predetermined pressure for each of the different forms of polymer materials. The different forms of polymer materials bond to each other at interfaces between the different forms of polymer materials. The polymer materials are cured to provide the integrally formed article of footwear and the article of footwear is removed from the mold.
