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.

SILVIA - April 09, 2026

Super comfortable!

Stefannie - April 07, 2026

Un classique indémodable!

Georgia - March 01, 2026

These fit like a glove. I am an 8 in women’s. If you wear thick socks it is snug. The sock I have aren’t super thin, but aren’t thick either and they didn’t make my foot feel snug or anything. I am going to get either the black leather or brown leather ones next. They are so cute!
