This is gonna sound crazy, but slather them with Crisco then put on cotton gloves. Hospitals often use Crisco (although they don't call it that on your itemized list and they charge out the wazoo for it) Aquaphor is also great.
Yep, I've seen that done at the nursing home where I work, but it was years ago. (Although I have no idea about the billing part, LOL.) One lady had terribly dry legs that would crack and bleed and they routinely used Crisco on them.
My hands and heels crack and bleed all winter long if I don't keep something on them. Vaseline (store brand) and Dove lotion have worked lately for me... but only if I use them daily. The Vaseline twice a day, the lotion whenever I think of it- at least twice a day, sometimes a lot more. If my hands are particularly bad I will cover the cracked parts in band-aids and neosporin overnight, and they are usually much better in the morning.
I've also learned that I can't use certain scented lotions (like Bath & Body Works) on those areas because the alcohol in the lotion actually makes my skin MORE dry.
DS is starting to have trouble with dry skin patches, and the doctor suggested Aquaphor/ Eucirin ointment. I've used it myself in the past and liked it. She also said not to use scented baby lotion on him for the same reason as I said above- the alcohol will cause his skin to be dry.
