Xero Shoes is about promoting the benefits (and comfort and FUN) of natural movement, first and foremost. Whenever we can, though, we make vegan-friendly products.
Sometimes we aren’t able to due to the materials needed to construct a shoe that meets the requirements  of jobs that require, say, a leather shoe.
At this time, the only shoes not vegan-friendly are the All Day Prio (leather), Tari (leather), Denver Leather (leather), the original Mika (wool collar), the leather Hana, the non-knit Phoenix (leather), the Prio Suede (suede), the Kelso (leather), Glenn (leather), and the Ridgeway (suede).
