Love it!

Bought them in Seattle while visiting family. Loved the shop and the experience there. The sale person was great and very attentive to my needs. I love the fact that I can grip with those sandals on all kind of terrain, even wet rocks! Best of all is that I can actually still feel the ground under foot but save my skin on rugged terrain. I got the tabis as well and it is such a great combo in wet and cold weather or if I just feel like a bit extra protection. I am not looking at anything else for a long time...

minimalistic sandals getting bloated?

I’m running in Luna’s since the first sandal they released. I always loved them for their minimalistic and simple approach. Yet, I find my latest purchase the Oso Flaco a bit disappointing. With additions like the “ATS Adjustable Achilles Gripping Pad” I feel the minimalistic sandals I love are getting more bloated every year. The sole also tent to mold less to your feet and feel more heavy on the foot.

AMAZING SANDALS!!!

These sandals are the straight up best. They’re comfortable, easily adjustable and priced well. Couldn’t recommend more

Moving all the joints in my feet

Second pair, walk, climb around everyday; high arches, no callouses except on the bottoms of my foot where they belong. These shoes are part of my structure.

Took some time, but then great!

It took a few days to find the right set up of the straps for my feet, and I was initially worried I had made a mistake by buying them, but once I had it they felt comfortable and secure on my feet. No pain when walking, and the rubber is reliably grippy on rocky and uneven terrain. I'm still experimenting with the technical strap, as it helps the heel strap to stay up but it also restricts my foot movement slightly. Great quality!
