In 1998, the CELL Alien boldly took our CELL tech further than it had ever gone before – literally. With its bubble heel, the CELL Alien was geared specifically towards long-distance runners, providing a stable cushioning effect with each step. This staple of ‘90s running crowds is making a comeback this year in its OG form. The responsive, supportive IMEVA midsole is there, as is the grip-tastic rubber outsole. All we’ve done is add a TPU hot-press PUMA Formstrip to the side to modernise the look.
