With what sourcing? She's 5'10" and her feet could easily be a 10. Now apparently this site will be the only source that says they're an 8. Sorry but my wikipedia background is creeping up. We shouldn't be changing information because someone thinks they "look" that size.
@Chombro you might want to dig down into the pictures before you upload. You uploaded this pic June 27/15 and I uploaded it (same size) over three months prior on March 7/15. Therefore, yours is the duplicate. Not mine, as some genius reported.
Usually size 10 is a little too big for my taste. But I am finding that even some size 10's can be ascetically pleasing. I think the width of the foot plays a huge roll in bigger sizes, like if a size 10 is too wide, then it looks overall too big. But if she has a nice lean skinny foot like Zendaya, then it totally works. She definitely looks better with nail polish, as do most women. Rock on Zendaya!!
