    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. ;-)

      Perfect Sandals

      These sandals do not slip or move on the feet while climbing on rocks or running. They are flat and thin, which is ideal for someone who grew up mostly barefoot. I really love them a lot. I have very narrow feet and the customer service person with whom I communicated by email suggested I go with the Retro version because I'd be able to pull it a little more snug. This was great advice and great customer service.

      Love 'em!

      I'm so glad I decided to give LUNA sandals a try after nearly giving up based on less-than-awesome experiences with other minimalist sandals. They feel secure on my feet and the grippy soles are perfect for wading through streams, climbing on slippery, moss-covered rocks, and all the other things I get up to on an average hike. Over the course of one weekend, I put in about 20 miles in my LUNAs, and my feet felt great. They're super easy to clean, and I love the perfect balance between ground feel and protection so I'm not wincing over every sharp rock. These are my new sandals for life!

      This is a quality product. I researched and compared these to others before purchasing. I am so glad I bought these sandals. I love that these are made in the US. Very durable and comfortable. I’ve used them running to and from the beach, lifting weights, and walking on pavement and gravel. Allow time for your feet to adjust to the sandals in order to avoid getting hot spots or blisters. The thinner soles help maintain ground feel and allow greater whole-foot movement. I bought these with the technical straps. I did not need those after wearing them once. I highly recommend these sandals. To add context I have been using minimalist footwear or no footwear for 10 years. Your experience may vary, especially if you are not used to minimalist footwear.

      Amazing customer support

      First of all this company rocks. I’m a terrible customer, first I ordered a wrong size, returned it for a new size but I accidentally clicked the wrong version of the sandal . I looked at the order and it was my mistake not lunas. So I had to exchange a third time for the right size and sandal. No questions asked, they paid for shipping which they should not have had to cause it was my mistake. Well today I finally got the pair I have been excited for. It’s the 10.5 men’s flaco. I have them on now and am hooked. Can’t wait to wear them in and hike with. I believe I am a customer for life and am thinking I should quit my high paying job to work for Luna. Who needs shoes? Thanks again Luna top notch service and sick sandal!!!!!
