Balenciaga's signature 'Speed' sneakers became an immediate streetwear hit when they debuted, and they show no signs of slowing. Made in Italy, this pair has chunky memory foam soles and lightweight stretch-knit uppers subtly patterned with the house's logo. Pick up the neon-green trims with one of the label's fluorescent hoodies, or keep it low-key with a monochrome sweater and skirt.
