Performance apparel and footwear brand while on earth™ today opened pre-orders of the Rhythm Runner, its first dedicated running shoe. Architected by co-founders Christian McCaffrey, Brooke Wells, Mat Fraser, and footwear veteran Todd Meleney, the Rhythm Runner is available now at whileonearth.co and retails for $160, with shipments beginning in June.

Following the strong reception of while on earth’s debut training shoe, the Move Trainer, which launched in 2024, the Rhythm Runner marks the brand’s entry into the running space with a silhouette shaped by direct feedback from its multiple highly decorated athlete co-founders. Designed for the steady rhythm of daily training, it combines comfort, stability, and effortless flow for everyday runners and athletes alike.

“We didn’t set out to make another running shoe. We set out to rethink what a run can feel like when every detail is considered through the lens of how people actually move day to day. We sought to build a shoe that doesn’t just support your run, but elevates it. That thinking guided every decision, from where to reduce weight to where to add support, and how to balance responsiveness with stability,” said Todd Meleney, Co-Founder and CEO of while on earth.

The result is a premium everyday runner designed for the steady rhythm of daily training. From tempo work to serious miles, sled workouts, turf sessions, and outdoor adventures, the Rhythm Runner combines comfort, stability, and performance to deliver effortless flow for those who move with purpose.

“The Rhythm Runner is the best running shoe I’ve ever worn,” said Christian McCaffrey, Co-Founder of while on earth and running back on the San Francisco 49ers. “Responsive, reactive, durable, comfortable. Throughout my career I’ve gone through a pair of shoes every 10 days. The Rhythm Runner has held its mold and value over countless high intensity sprint sessions. As an athlete, everything starts at your feet and it is so refreshing to know my shoes allow me to do what I love.”
