    Super impressed with the Osos simplicity, comport and durability. I use them trail runs and general wear with zero discomfort or issues. Great tread pattern offers a secure feel on uneven ground with no slippage. Osos shed dirt and debris easily so no sore footbed! Well worth the investment and so impressed, I picked up a pair of Monos. Advice: I went down to a size 9 since I normally wear a 10.5 in a running shoe...customer service was outstanding assisting in a fast exchange.

    Best Luna yet!

    I've lost track how many Luna's I've owned. Somewhere around 10, and these are the best yet. I'm primarily a casual wearer and occasional trail runner in my Lunas, and these Winded Lunas are excellent. Easier for casually getting on. Sole has insane grip on the trail. Perfect

    The OSO FLACO's were great before... now they're even better. I like the additional colors and greater ease of entry. The Vibram Megagrip tread, skinny stack height, and improved lacing system make these perform like a dream.

    Great fun on a recovery run/walk trying out the LUNA Sandals new winged edition of the Oso Flaco - its been a long time since I used standard lacing system, I switched to traditional lacing about 5 years ago, as I found this kept the sandals more secure on my feet - the winged version however seems to hold the straps in place without any tec strap, certainty they have adjusted to my feet immediately and held in place. I am always a huge fan of the original mono & venado as I love how they mold to your feet & on first inspection of the Oso Flaco -I did wonder if it would be flexible enough to mold, but running on softer trail you can feel a real give of the sandal working with your feet. Unfortunately my trusted Leadville Trails are no longer an option in the Luna range - I currently only have one pair which have seen me through 6 100 miler finishes and all my other distance races over the past 3 years, so while they are still in good shape - I did need a second option for this years big adventures - I think I may just have found them ! Thank you Barefoot Ted & the Luna team for giving me the opportunity to trial !
