I had never heard of these shoes, but since I am in shoe-review mode these days, I took a look at their website and found a few reviews. I thought this was a very helpful review,

Turns out these are described as minimalist, zero-drop shoes. I just wore a pair of zero-drop for about 1000 km, but they were Altras, referred to in the review as not eactly minimalist but in the same vein.
What sold me on the Altras after using them was the exceptional cushioning, which these shoes don't have. BUT they do have a 5,000 mile warranty on their soles. That's pretty amazing.
Based on only my one camino in Altras and several months beforehand obsessing about shoes, I think these Xero shoes would be good for people who are comfortable with little cushioning, and who don't need an orthotic. I know that all the zero-drop shoes are touting a return to the natural barefoot footstrike, but for people with mechanical deformities in the construction of the foot, orthotics are necessary. And Altras worked fine with my silicone orthotic (even though it must have thrown the zero-drop out of whack, no?). Not sure if Xeros would.
It sounds to me like these shoes are one step up in terms of construction from the five fingers. We had a few threads years ago with people who had walked in those, but nothing recent.
Arbey, have you used these shoes in other situations? Is there a specific reason they appeal to you?
Thanks for introducing us to another shoe option! Buen camino, Laurie
