No Shoes? No Problem: Running Ultras in Crocs with Steph Smith

In this episode of the Happy Cast, hosts Stephanie Leake, Dylan Rueff, and Andrew Marvin sit down with ultra runner Steph Smith, who has taken the trail-running world by storm—by running 100-mile races in Crocs. From her early days as a marathoner to her first ultra, Steph shares how she discovered her love for endurance racing and why traditional running shoes never quite worked for her. After experimenting with barefoot running and minimalist sandals, she made the switch to Crocs and has never looked back.

We dive into the mechanics of running in Crocs, the modifications she’s made (including adding rugged Vibram soles), and how they compare to traditional running shoes. Steph also shares her experiences at races like the Badger 100, Midwest States 100, and Tuscobia Winter Ultra, where she’s tested the limits of both herself and her unconventional footwear. Plus, we discuss the ultrarunning community, the importance of race traditions, and the mental strength it takes to keep going—whether you’re running in Crocs or not.

Beyond the gear, Steph talks about the camaraderie that keeps her coming back to the same races year after year. She shares stories of bonding with strangers on the trail, the unique challenges of winter ultras, and the magic of smaller looped races where every runner, fast or slow, becomes part of a shared experience. We also touch on the problem-solving mindset that ultrarunners develop—whether it’s troubleshooting blisters, adjusting nutrition, or deciding to run in something completely unexpected.
