Thanks for all the replies. I guess that's what I was expecting.
I know there's no real alternative for leather, especially a high-quality leather -- but I'm more so looking for something that is a decent alternative. I.e. When I order a veggie burger(yes,


), I'm not expecting something comparable to a hamburger, just something that tastes good.
As for noharm, not really what I was looking for but thanks for the suggestion.
I'm not sure if the Common Projects have a leather sole or not, but that's the type of shoe I'd look towards getting at this point.
As for animal glue; It's not too hard to find suitable alternatives and from the experiences with shoemakers/tailors I have dealt with in the past.. I don't think they would have an issue with finding one or using one that I provide - thanks for bringing it up, though.
Leather products from natural death/salvaged leather would be a great second option -- I've looked for these types of products but had no luck. Do you know any companies that provide these products?
