I'll offer some thoughts, in no particular order, to accompany this pic, which I find one of the best of this girl's feet.
-I, too, have always found her feet to appear a bit little-girlish, tho I also think she has grown into them in the last few years.
-Her feet are very long and slender for a purported size 8.5 US. This gives the appearance of stubby toes, which I find somewhat inaccurate.
-Her propensity for very high heels shifts the weight forward and her toes tend to hook a bit in such shoes. Indeed, I have never seen a pic of her feet in shoes that I found as attractive as pics of her bare feet. The peep toes are the worst, to me.
-When barefoot, her toes seem to relax a bit, and do not appear, to me, to be stubbly at all. Her toes look very different in this pic ----->
-I agree with some that her nail care seems to be a bit of an afterthought. But she no longer seems to use an electrician's wirecutters, or a weedeater, to trim her nails, which lessens the appearance of toenails ripped off like a child's. Unlike say, Britney Spears, her feet get better with time, in shape and proportion.
Her feet have grown on me, and I would not kick her out of bed for eating crackers.
