Puma | CELL ALIEN KARL For Brothers the Trefoil has stood forDuring the 1990s, PUMA introduced the first iteration of its CELL technology. Innovated with the structural integrity of a hexagon in mind, it provided a shoe with stable cushioning one that could support stronger, more dynamic movement. In 1998, the CELL Alien was released.
