I’ve purchased 8 pairs of these shoes. They are awesome. They are high quality. They last.
I have three winter pairs of vivo's. They aren't as warm in winter as Xeroshoes, so I mostly use them for hiking in fall and spring. They last forever, and are very comfortable. If you have warmer winters, these are perfect.
Xero is based right here in the US. Vivo is in the UK.
