Have you ever looked at a girl and decided how attractive or unattractive she was based on one factor? Maybe you are a "breasts" guy, but you find yourself drawn to a hot girl with a small chest because of other things, like the way her nose scrunches when she laughs, or her soft hair, or the way her hips move whens he walks.
Women are the same way. There is no mathematical formula to sexual attraction. No matter what the girl personally thinks about smaller hands and feet, she will look at you as a package deal. The qualities that she considers attractive in you, whatever they may be, will be what she focuses on. She will accept you because of EVERYTHING, not just one factor.
And it isn't just "smaller" girls who are interested in smaller guys, by the way. Lots of girls see many attractive features in men despite their size.
If a girl turns you down solely because of smaller hands and feet... than she isn't worth your time and attention anyhow. There are lots of fish in the sea!
(I'm not just saying this stuff, by the way. My boyfriend isn't very tall either, and has "smaller" hands and feet. This really doesn't matter to me. I think he's sexy as heck.)
I feel your pain. I wear an 8 1/2 shoe size, I'm 5'9, and I also have pretty small hands. On top of that I'm only 120 pounds but still in shape. If you were to ask if I feel unattractive because of the features I'd have to say probably not. The thing that would bother me the most is being shorter than the girls I liked. Since I'm 5'9 I'm usually taller than most girls I like or at least the same height. You have nothing to worry about though, just have a good personality and girls will fall for you.
