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 Alston, Melbourne, leather Hana, leather Phoenix, which are made of leather, as well as the original Mika, which contains a small amount of wool on the collar. We previously had the Coalton (leather) and Pacifica (wool), though we no longer carry those.
