Heads up Nike Metcon fanatics, the new cross-training sneaker you’re all going crazy for and buying up faster than how long it takes somebody that does CrossFit to make sure you know they do CrossFit arrives in another new colorway. Hitting sneaker store shelves is the lean and mean training shoe in a four-way block of Midnight Navy, Game Royal, White met by the Volt sole. But act fast, because if they follow the trend of previous Metcon releases, they won’t last at retailers like Finish Line long. Granted the production numbers are far less than that of LeBrons, but these do-it-all gym shoes are selling out incredible fast.
