I just saw that the shoe company Globe has some leather-free skate shoes, and the website states that they are vegan-friendly and made without animal-source components - that would mean not just leather-free but also no animal-source ingredients in the glues or rubber.
The info below is from the Globe website. Note that ONLY THESE COLOURWAYS ARE VEGAN.
