Vegan and pre-owned leather?

[Ci?ra Star]

Right, recently just become vegan in the past couple or months or so anyways. I've always lived in boots (leather). Always, and I don't really know were to stand with them anymore. I mean it's obvious that vegans do not support leather in anyway, so it's be wise to throw them out. But on the other hand that would have been a waste of an animals life, so I'll simply be wasting it. SO should I continue to use the boots I have until they wear out or throw them out completely? Same with woolen jumpers? I really don't know where to stand with them.

Also accidental buying of animal products, y'know if your in a rush or something and you can not take it back, throw it or consume it?
I'd like to know all your opinions on the matters
