Wider feet?

We expanded our collection to include wide-width styles that marry comfort and style. This selection of products is available in extended widths that provide additional room across the top of the shoe, where your foot naturally bends.

Half Size?

Sizing may vary between style and type of footwear. Half sizes are not available in all styles.

Unisex sizing?

Some styles are listed in traditional men’s sizes. For traditional women’s sizing, subtract 1.5 from the listed size.

Midi vs Regular Rings?

Our regular rings are designed to be worn at the base of your fingers, whereas midi rings are smaller and meant to be worn midway down the finger, between the first and second knuckle.
