This is a good fit.
This is a good fit.
This is slightly too big; we would recommend a half size smaller.
This is a good fit.
This is much too large. We would recommend 1-1.5 sizes smaller.
This is too small. While we like a close fit, we don't want your toes hanging off the sandal! We would recommend a size up.
Though some people are happy with this fit, we would recommend a half size bigger.
Harmony 783
Sizes are listed in US sizing, with W for Women and M for Men.
Unisex styles show both equivalents (e.g. W9/M7.5 = Women’s 9, Men’s 7.5).
If you are between sizes, we recommend choosing the half-size larger. Shoes that feel snug at first will typically relax and form to your feet after a day or two of wear.
