Adidas has rethought the standard EVA foam midsole and have changed the world of running with their Boost technology. 2,500 plastic pebbles are fused to create a material that is springy and provides the most cushioning to date. The adidas Energy Boost ESM is a top-of-the-line running shoe that offers a bouncy and lightweight ride in a clean all white colour scheme. The shoe is accented with small hits of black on the outsole and lace tips as well as a small purple insert along the inner midsole. You may have seen these during Kanye West's impromptu performance at the United Center.
