For me, women seem more naked when they wear shoes. Heels, sneakers, anything is better than bare feet. 
Fully naked is like a nudism principle and I can't even watch it, but nude with shoes is more provacative. Like she covered her feet but left the rest off intentionally, she did it on purpose. It's naughtier and more exciting. 
What say you? 

I understand what you mean, and I respect your preference, but for me it works completely the other way around.

To me, a woman looks more attractive barefoot or wearing something simple like flip-flops, because it feels more natural, relaxed, and real. Shoes — especially heels — usually ruin that feeling for me. Nude with heels doesn’t feel more provocative to me; it feels too staged, too artificial, almost like a costume or a porn-style pose. Instead of making it more exciting, it actually lowers the excitement for me.

What I like is the naturalness. Nude and barefoot feels more intimate, more spontaneous, and more authentic, like she is comfortable being herself rather than performing a look. Even if her feet are a little dirty from walking barefoot, I find that more real and appealing than polished heels or shoes.

So I get why shoes make it feel intentional and naughty for you, but for me that “intentional outfit” effect is exactly what makes it less attractive. I prefer something simple, natural, relaxed, and unforced.
