In searching for clothing and shoe companies, I have found there are many companies that seemingly care about ethical treatment of all animals (furry and human alike) and beng made in the US or in positive foreign factory envirnoments, but on closer inspection they raise questions for me. For example, New Balance was founded in the US and retains five factories here, but the materials are not from here and there is no explanation on content of said shoes and practices (animal rights, eco-safe, and the like). I stumbled across an interesting article to share, while searching for viable clothing and shoe sites for this section.
