For all feet shapes and sizes

For all feet shapes and sizes

“We wanted to create a running shoe that fits to all types of feet and provides ultimate comfort”, explains Co-Founder and 6-time Ironman Champion Olivier Bernhard. “So many people struggle with finding the perfect running shoe. With the Cloudster and its Adaptive-Fit concept, we wanted to empower each runner to run the way he or she was meant to run. This means freedom for your feet, putting you back in control.”

A true all-rounder

A true all-rounder

The Cloudster was launched in 2012 to appeal to a broader audience of runners who already valued the CloudTec® sensation, but were looking for more of a starter model to play and have fun in. The redesign in 2015 made the Cloudster a true all-rounder: for every runner, every run, every size and every foot shape.
