ADIDAS X HELLO KITTY MULES TO CELEBRATE A MILESTONE. Celebrating Hello Kitty's 50th anniversary, these adidas Stan Smith x Hello Kitty shoes fuse iconic sporty style with whimsy. Originally made famous by the '70s tennis star, the Stan Smith look has become a symbol of casual style that's carried through in these mules. Hello Kitty's face stands out, accented by a cute silicon ribbon for a playful touch. The foam construction keeps things light and cushy underfoot, with a slip-on design so you can quickly slide in and be on your way.
