Fantastic Sandals!

I've used it several times
Size Bought:
6' 2"

After being through several pairs of sandals that I wasn't a fan of I stumbled across Luna. The Oso Flaco in particular seemed to be the perfect sandal on paper. If you enjoy a minimalist fit and low profile feel then these are for you. they are incredibly comfortable for how thin they are and easy to adjust the fit for optimal lockdown on the heel. The vibram sole is great if you need to take these on a trail or anywhere that requires a bit of extra grip. Fit feels true to size. I wear an 11 in street shoes and got a size 11 in these and have no complaints so far. I believe Luna was born from a running background, and while I have not used these sandals for running, I have used them on my bike and walked several miles in them at a time with no issues.
