    Size Guide
    LUNA Sizing
    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 support@lunasandals.com
    The biggest issue people have is not having the template accurately printed, so double check twice. ;-)

      LOVE these!

      My first Luna sandals (purchased with Oso 2.0 for hiking), won’t be the last. They have made it so that I dislike my other shoes intensely! I love how they feel a part of my foot, my foot made better. Wish they made something for snow and cold hiking! Luna, any chance?... Ordering Brujita next :)

      Finally found my perfect outdoor sandals!

      I barely broke them in and hiked 2 miles, then 4 miles and NO BLISTERS! I have tried Chacos over and over and they gave me blisters every time!! But the flacos are thin so that you can wear around town and have a great hike in them. I’m in love thanks Luna

      Great sandals!

      LUNAs Oso Flaco are really comfortable, and they have an incredible grip. I am very impressed with them and happy with the purchase.
