The PUMA RS-X3 ‘Emoji’ features a playful design theme inspired by the digital icons used for shorthand communication in the internet age. The lifestyle runner utilizes a breathable black mesh upper, accented with iridescent no-sew overlays and a grey Formstrip outlined in contrasting yellow. Replaceable emoji icons can be attached to the heel panel for a personalized look. It all rides on a bulky foam midsole, outfitted with contrasting TPU pieces in yellow and black.
