Find Your True Fit

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.

Oso Flaco Winged Edition 🇺🇸 Highlights

LIGHTEST WEIGHT

EXTREME GRIP

THIN YET RUGGED

DESCRIPTION
For those who demand the best in class performance focused minimalist footwear that can handle the BIG adventures, the Oso Flaco is super attractive.

Using our specially developed Vibram Megagrip studded tread, we've built a sandal that can handle the complex world of real adventure: mountains, rivers, trails, mud.
SPECIFICATIONS
Made in: Wenatchee, Washington, USA.
Mighty Light: 7.2 oz (single sandal, men's size 9).
Dig in: 7mm base + 4.5mm lugs.
Best in Class: Waterproof Non-Marking Vibram® Megagrip Outsole.
Get a grip: MGT (Monkey Grip Technology) footbed + Vibram® MegaGrip Outsole.
Ready to fly: Supple, easy adjust performance laces kicked up a notch by our super secure wing design.
Move Natural: A free foot is a healthy foot. Always zero drop, zero toe-box, zero problems.
Vegan Friendly: Animal free product.
Refined Simplicity: "Everything you need, nothing you don't."
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.

For more detailed guidance and support, please visit our size guide.

Today keep the tradition alive by offering a full line of "Made in USA" sandals from our newly built factory in Wenatchee, Washington.
