How do I get new (or used) hiking boots/shoes as low waste as possible?

I would love any advice people have on where and how to get decent used hiking boots or trail shoes. I know there can be issues with used hiking boots probably, but i’m not an avid hiker or anything I just want something that’ll last me when i’m in the field at work and doing casual hiking. Something waterproof is ideal too.

Buying new shoes in general is so hard for me, because I hate buying stuff not second hand, I want something at least somewhat sustainable, I want vegan shoes, and i also have pretty wide feet too ugh. I don’t want to be unrealistic about what is possible to find, but it’s important to me that I do the best I can. I already had to get muckboots for work, which didn’t meet my “requirements” of being vegan, used, or sustainable, but my work bought them so I tried not to stress too too much. I want to do better for some hiking shoes though.

Any advice would be greatly appreciated, thanks!
