Sizing and Fit

Sizing varies among our styles, with our sandals being narrow to medium width and available in half sizes, and our shoes being a medium to narrow fit for Women's and medium fit for Men's, and available in full sizes.

We strongly recommend printing the templates (where provided) below to check your foot size and ensure a perfect fit!

Our Men’s styles are generally a medium fit and will stretch out after some wear to accommodate slightly wider feet. Ordering half size larger than your regular fit is recommended, especially if you intend to wear the shoes with socks. Ideally, initial fit should be tight but not uncomfortable. Our shoes have no internal reinforcements and the natural leather will stretch and take the shape of your feet within days to a few weeks depending on frequency of wear.

We've found most customers report that our sandals run slightly small. If you have a wider foot or are between sizes, we'd suggest sizing up to the next half size. 

Instructions for templates:

Choose the most appropriate size and print out the corresponding template (printable file). Place your foot on the template so that the toe hole is between your big toe and second toe.

Use a pen or pencil as a place holder. With the pen or pencil in place, make sure that your toes don’t go past the front of the sandal and that your heel doesn’t go past the back of the sandal.

If everything seems to align, this is the right size for you. You’re ready to order! If something didn’t align, try the template next size up.

Comfort and Fit

Clay Shoes

You will notice that the insole has stitching along the edges. This Beeswax-coated twine is an integral part of the construction of the shoe and is what allows us not use cements and glues to attach the different parts of the shoe. It is completely normal to feel the twine and it will soften with use. The more you wear them the quicker they will soften. If they are extremely bothersome try wearing them with socks which will speed up the break in period. When wearing them with socks, the stitching is hardly noticeable. Wearing natural cotton socks will still provide grounding!

Sandals

Some of our sandals are padded and some are non- padded. Our non-padded leathers can be sort of stiff until broken in. An all-leather sole however, will feel better and better over time because it will begin to mold and compress to the contours of your foot so that it feels well secured, yet cushioned. Same goes for leather bottom soles and any upper straps that will soften and mold to your foot. Break-in can take 1-2 weeks, after which you will want to wear no other sandal!


Our grounding footwear is handmade using natural materials. Some styles may feel tight at first but will break in and stretch and soften over time. We’re confident that after you try on our grounding shoes and sandals and experience the benefits of grounding you’ll fall in love! Try them on around the house for 30 days! Still, if you aren’t entirely happy with your order, you can return your shoes or sandals within 30 days for a full, hassle free refund. Visit our Shipping and Returns page for more information.
