I have tiny feet too and although I like the split fin at first, I'm using the Azione by Akona now, and love them. I don't cramp, and yet when I need to chase after something, like squid to get a good photo, I have the power to get there. So much so that my "husky" buddy ended up getting a pair, as I can keep up with his fining which has a greater stride than mine. I'm wearing the full foot, and using the Akona socks with them. Hope this helps.
