    First timer.

    My first time to run in them. The right foot offered no problems. The left not so much. The strap edges between the toes folded away from the skin on the right foot...the left foot not so much. The strap edges on the left folded in toward the skin and rubbed the skin. I was able to reset it but with difficulty. And it continues to require adjustment. But I think I have it solved.

    I think Oso 2.0 takes time to adjust to our feet. The footbed is quite solid, my first week, try on a city run it’s make my feet underneath have blisters.

    Grip eccellente ma sandalo più pesante e meno flessibile.

    Questo è il mio primo Oso 2.0 che uso nelle mie uscite di trail running. Dal 2015 ho usato i Leadville Trail (leggerissimi e con buon grip), i Mono 2.0 (eccellenti per la strada) e i Mono Gordo (compagni ideali per le lunghe distanze). Rispetto a questi modelli gli Oso 2.0 hanno un grip perfetto ma la consistenza della suola li rende meno flessibili e secondo me più adatti per l'hiking ed il trekking. This is my first Oso 2.0 for my trail run. Since 2015 I've worn Leadville Trail (lightweight with good grip), Mono 2.0 (excellent for road run) and Mono Gordo (one better for the long distance). Compared to these models, Oso 2.0 is a sandal with perfect grip but the sole has a hard consistency that makes them less flexible and in my opinion it's more suitable for hiking and trekking.

    I've never been this happy with any footwear

    This is such a great product, I've been going crazy with them. As very wide footed person, I've been cramped in shoes my entire life, up until today. I'm now free.
