The Circadian will keep you secure and in tune with the earth’s natural rhythms—at every step. The minimalist nature of Earth Runners sandals offers a gentle reminder to yourself–and others–of the oneness you share with the Earth.
The Performance laces featured on the Circadian Adventure sandals provide ultimate security and longevity on all of your adventures, while the thinner & more flexible Lifestyle laces on Circadian Lifestyle Sandals are ideal for maximum comfort in casual everyday life. *The only difference between Adventure and Lifestyle sandals are the laces.

Can the Circadian model be worn in water?
Yes, all of our sandals can be worn in water. The Earth-Grip footbed resembles the feel of a mild bare earth equivalent--with superior all weather traction. The 100% cotton footbed will hold some water weight until it has a chance to dry. In comparison, our Elemental model dries much quicker by featuring no Earth-Grip footbed but the trade-off is less effective grip/performance in water.
How do I decide between the Circadian Lifestyle Sandals or Circadian Adventure Sandals?
The only difference between these two Circadian models are the lace, with the performance laced (adventure) sandals costing $5 more than the lifestyle laced edition. The lifestyle laces offer slightly more comfort while the performance (adventure) lace is more burly & secure. They come in different color schemes which may be a deciding factor.
Why is the Circadian the most popular Earth Runners model?
The Earth-Grip footbed provides a comfortable secure experience along with ideal light weight, proprioceptive feel and aggressive traction. These factors work in concert to make the Circadian at home in the backcountry or around town.
Is the Earth-Grip footbed Organic?
The footbed is dyed in small batches using GOTS certified organic dye in Los Angeles California. The fabric itself is not certified organic. The farmers in India who grow our cotton use traditional practices that have been in place for over 100 years--before non-organic fertilizers were introduced.
We laminate the Earth-Grip footbed to the Vibram® outsole using solvent free thermal adhesive.
Earth Runners are inspired by ancient huarache running sandals. We are grateful to the Tarahumara for originating this design and feel fortunate to have the ability to give back and honor the creators of the huarache running sandal.
