Yes. Isolating one part of the body never did a thing for me, especially if it was on a guy who was showing his feet, bug giving the camera the finger.
I prefer to see a whole person, the same as I do on any site I have a profile on. Even photos of a guy's full body, without his face, are a turnoff for me, since I know the guy is in the closet, or he'd show his face, and I want to see his smile. Even a non-smiling guy with beautiful feet is like getting sourness along with the great feet. So, an average-looking guy who's smiling, and has great feet is more of a turn-on than a great-looking guy with great feet, but looks bored or angry.
Smiles cost nothing, but are priceless in their impact. Get yours today!
