    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. ;-)

      Good so far

      Really love the look and feel. Not sure what rating I’ll give them yet though, the sandals make my feet hurt. I think I may just need to adjust from moderate support to no support. Fingers crossed this is the issue and as soon as I work on it, they will become my favorite running sandals. For right now I’ll stick to hiking in them.

      An absolute winner!

      I bought a pair of winged Osos in 2019 and love them. They are amazing on rocky trails and provide a reassuring level of protection to your feet from pointy rocks and other hards objects on trails. However, as my weekdays runs involve mostly paved surfaces in an urban environment, I was looking for a pair of sandals with a bit more flexible sole and the “wing”, so I tried the Oso Flaccos. They are absolutely perfect! At 11 mm (compared to 17 mm for the regular Osos), they are more flexible and more comfortable to run on hard surfaces, but also to walk. As a result, they have barely left my feet since I’ve received them, and since they performed better than expected on the little rocky trails I’ve run on with them so far, I might just start all my runs with my Oso Flaccos and bring the regular Osos for longer portions of trails. My best running gear purchase of 2020 so far!

      I sent an email out during the shipping process. I stated that I needed the sandals in a couple days for a race that I had entered. I asked if there was a possible way to get those shipped soon. I soon received an email regarding that they had been shipped. I didn't receive them in time but I wanted to give a thanks. Luna Sandals, showed great customer service. They demonstrated value to my business and they went the extra mile. Thanks!

      Excellent sandals!

      First pair of Lunas and they are awesome! I’ve put a few miles on them and they are holding up great. One small issue I had is that the toe strap is slightly off from the other one in relation to the inside of the sandals. Not worth dropping a star for, but my OCD won’t let me get over it. Strongly recommend!

      Always the best and keep getting better

      This is my 3rd pair in about 10 years. Has it been that long? Anyway, they were always an exceptional product, but this latest pair has really kicked it up a notch. The strapping and sole are better than ever. Love my Luna’s!
