Size Guide
LUNA Sizing - SIZING CHARTS - shoe size
THE SIMPLEST WAY TO DETERMINE SIZE.
MENS SIZING IS NEARLY ALWAYS 1/2 SIZE SMALLER THAN REGULAR SHOE SIZE AND WOMENS SIZING IS USUALLY TRUE TO SIZE. 
Once you've determined your size, you can double check it by clicking the corresponding Printer Iconand printing out a template.
When printing our copyrighted PDF templates, make sure the "Scale" in the Print Window is set to 100% or the template won't be accurate.
If using the Chrome browser, make sure the "Fit to page" checkbox is UNCHECKED.
After you print out the template, also double check the scale by comparing a ruler to the ruler that prints on the template.
Toes should be close to edge, but not hang over. Want our opinion? Send a photo of your foot on the template to support@lunasandals.com or message directly from your phone to 855-586-2726 <<
The biggest issue people have is not having the template accurately printed, so double check twice. ;-)
We can also send you our sizing templates. Order here.

SIZING & FIT
Most men tend to size down 1/2 to a full size with LUNAs.

Most women are true to size.

With LUNAs, you want a close fit and not a lot of space around your foot.

    WOW!

    I hiked Mt Marcy last weekend in these sandals. The trails were very wet and muddy, but I was amazed by the robustness of these sandals. Even on the slick wet granite, these sandals kept me firm in my place.

    Worth every penny!

    These have quickly become my new favorite sandal! I’m a dog walker & these are excellent for every day, all day wear in my opinion! The straps are comfortable, and the part in between my toe doesn’t bother me at all - I haven’t worn thong style sandals in over 8 years but these are so comfy. I find these super stylish and versatile. I wish there were a few more color options but that’s it. Also 100% appreciate the Made in USA options, that’s what I buy!!
