If you thought the adidas Energy Boost was a game-changing runner, just wait until May 14 when the Three Stripes releases the Extreme Energy iteration. While we're not certain what the sneaker looks like, based on this recent adidas teaser, the new runner will be outfitted in a textured upper with the Energy Boost's signature foam-cushioned midsole. If its Extreme Energy name is any indication, we expect this Boost sneaker to be an epic adidas release.
