Nice. Yeah, I have vivo too but looking for sandals and ideally copper and leather soles. Good for you on the barefoot. I have been almost 98% exclusively barefoot the last month and so so grateful.

Ok so I actually checked vivo and they have a leather soles sandals...https://www.vivobarefoot.com/us/san-dal-ii-unisex?colour=Obsidian

The price is quite steep... But I might consider it still. Gonna do a bit more research. And check out campers.
