Here at Seeded Sandals, we've had some questions about the fit of our shoes, so we figured we'd do a comprehensive guide.
As of right now, we offer only standard-width European styles. We've found this Wikipedia graphic for shoe size conversion to be extremely helpful and accurate in converting your US size to the European standard.

While we don't offer any wide styles, if you have a wider foot, the shoes that will suit you best are those styled most like a traditional flip-flop--Vine, Iris, and Saffron. Those with a band wrapping directly around the foot (like Mangrove, Meadow, Hibiscus, and Bouquet) should be ordered one size up.
If you have a narrow foot that falls to the low end of one of the sizes when looking at the shoe conversion chart, we recommend going one size down. For example, if you usually wear a size 8 in US sizes, you would be better suited to a size 39 rather than a size 40.
If you have any questions about sizing, please feel free to contact us at info@seededusa.com and we will do our best to figure out what size and style will best suit you. And as always, if a pair doesn't fit, we will be happy to exchange it for you at no cost.
