If you like something with more fragrance, I tried some of that Body Butter at Bath & Bodyworks. (Any of those type of stores carry 'body butter'.) It's very thick and creamy and doesn't take much. But it works like a charm and smells wonderful.
My feet are the same from our pool, me running around barefoot, and the drugs I take for the brain tumor. This body butter I've found lasts a long time and works very well. You can get it in multiple fragrances. I don't have to put socks on with this, and a good thing - I HATE having my feet covered with anything!
Hope something suggested helps. That's pretty miserable :(
