This post serves as a record for those who, like me, are searching for high quality vegan athletic shoes. New Balance (NB) produces several such shoes (although they may still contain glues made with animal ingredients), although this company has also been linked to overseas sweatshops. This website lists those NB shoes which are made in the U.S., and therefore are least likely to be made in sweatshops. I have indicated U.S.-made shoes in bold.
This list comes from New Balance customer service.
