My boyfriends peeling, dry feet?

My boyfriend likes to skateboard a lot and he's been doing it for years now. His feet are all peely and hard and dry. In between his pinky toe it ripped and its not scabing up so he's pretty worried. His pinky toes are really messed up. His toenails for his pinkies are like shifting off and they are very gross looking. I told him to put vasaline on his feet before he goes to bed (with socks of course) but he doesn't have any. I just want advice on anything I can give him besides lotion and if I should buy him vasaline?
