The Luna Sandal Oso could very well be the answer to a long day on the trail. I wanted to try this pair of footwear for its unique tread design and new lace options. After receiving them, I put them through some quality testing in the Olympic Mountains.
2017 Update: In spring
Luna will launch Oso Flaco and 2.0 Sandals (updated models).

| I found the tread good in all terrain types tested; besides for being a little slick on smooth wet surfaces. Appreciate how Luna pre ground the nose of the sole; this prevents extra catching on objects. Pattern holds a bit of dirt, you can see how there is still rainforest debris in tread. Found them not to clog however. |

| Improved Luna Trail lace. The previous elasticized lace was for convenience, this version is for purpose. Found them to hold my feet very secure to the footbed. A considerable advantage on uphill grades. The sewn in grip; aids in the prevention of the lace falling off your heels. |

Final Thoughts on the Oso (1.0)
I recommend the Luna Sandals Oso for those who are doing a lot of miles, on hard or sharp surfaces. They do a great job of hiding the feel of the ground. However, you do have to account for a weight penalty, for that extra protection.
