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.

    Most comfortable footwear I’ve ever owned

    These sandals are flexible, with excellent road feel and grip. I use them for everyday, travel, light hiking, and running.

    Well Made. Not for wide feet bring back custom sizing!

    I bought my Monos back in 2015 and at the time Luna made custom fit sandals utilizing a foot tracing. I have a 4e foot and being a minimalist/barefoot shoe wearer knew that off the self models would be far to narrow. So I sent in my foot tracing and paid a little extra and had the perfect sandals 4 weeks later. I have worn the soles to the footbed and I thought I'd give the Flaco's a try even if my foot would over hang 1/8". As soon as I opened the box and pulled the Flacos out I knew this foot bed is for really narrow feet. The length was on the money but the side of my feet hung over the foot bed by more than a half inch. I thought I was going to be a life long Luna customer but to my dismay they no longer offer the custom fitted sandal option. Once again people with Wide feet are nudged out of the market and options to minimalist shoes and sandals. I understand that such options are expensive to maintain and operate, but I am willing to pay an outrageous and overly excessive charge to have this option. Luna Sandals are by far the best constructed Sandals I have every worn and I NEED A NEW PAIR!!! I have other brands but they are not as good and well made or as comfortable. I want my LUNAS!

    What’s a Flaco anyway

    Love the sandals. Can only do about ten miles on technical AZ terrain though before feet get a little sore. Makes running in Oso’s seem oh so ez.

    Good feel. Great grip

    I like a thin flexible sandal but most don’t have enough grip for the area I frequent. These are great.
