Upper: 25% recycled polyester, 36% polyester, 20% viscose, 14% spandex, 5% silk

Interior Lining: biodegradable UMORFIL Beauty Fiber, a collagen-infused yarn suitable for next to skin wear, even for sensitive skin!

Insole: Felted Australian merino wool top for next-to-skin softness. Two layers of recycled foam: a base layer of high-density foam for support, and a midlayer of springy foam for cushioning in a low-drop design.

Sole: Matte black rubber for range of motion, traction, durability and comfort.

Our Tabi Sneakers run true to size. If you size down, your foot will likely "fit" due to the upper's ability to stretch, but you may experience rubbing at the heel.
