The PUMA x TETRIS collection sees the RS-X in daring colours inspired by the game, with falling Tetriminos sprinkled across the heel. Reflective trimmings and a 3D heat-cut TETRIS tongue logo add to the striking look of the RS-X. The phrase “HARD DROP” printed on the RS-X’s 3D heel, is a nod to the command in the game, which makes the Tetriminos land instantly.
