i have the exact same problem! i bet your feet catch on carpet fibers too? and forget about putting on a pair of nylons! i can sometimes slide on the wood floor because my feet are so dry. my hubby does too. it doesn't bother him at all but i cringe when i can hear him put on socks.
anyway, i was using the 'as seen on tv' miracle foot cream that they sell at bed bath and beyond until i found that is has parabens in it so i switched to a cream called 'almost butter' by kiss my face. that's works pretty well too.
i use a foot file first. i used to use it dry until someone told me you were supposed to do it wet so now i do it in the shower or when i'm taking a bath. it does work much better that way, my feet feel way smoother.
good luck!
