New Balance is tearing up the performance running charts thanks to some extremely colorful makeups, especially on the 890v3. It’s not something we’ve seen too much on the classic models, which makes this new pack of New Balance 574s stand out from the pack. The ‘Rainbow Pack’ 574s are split evenly between mens and womens colorways, all of which are rich in multicolor gradients right down to the laces. Check out all four after the jump, then seek out your Rainbow 574s at Extra Butter.
