As for the boots thing... well you know I love me bootsand I have no real qualms over buying leather goods these days but as a vegan I used to wear non-leather shoes. Bloody uncomfortable too I might add!
The issue of the boots can also go deeper. Which one is worse, killing a cow to make clothes, or using and wearing petroleum? I think that PETA threw a fit when Greenpeace said it was OK to wear leather (environmentally that is, fashion taste is another issue).
