which is even better if you're still at uni, you can tell the ladies that you need to see their feet for a modeling reference... (if they don't buy that tell them you're an illustration major looking for sketching for a prospective shoe conglomerate) and if that doesn't work, go to a party with lots of friends and just take pictures no matter what you need, cause eventually you'll find something that will fit your needs... be it feet in sandals, feet in high-heels, bare feet, etc. you'll need to see how the muscles in the feet react to their stimuli either way
