All the cool kids moisturize their feet and toes. 
It also will help prevent hangnails. All you can do for current hangnails is to cut them (but not too close to the skin), and possibly bandage them if the area is tender. If hangnails are a problem for you, then you may have to moisturize (with lotion, oil, body butter, etc.) more often than normal people. Start out with once a day, if that doesn't work then go to twice per day. If you're still getting horrible hangnails, then switch to thrice per day. Maybe switch your shoes or socks. They might be making your feet too hot/dry. If THAT doesn't work then see your doctor, because let's face it: nobody on the internet is credible.
Hope that helped!
