Cracked heal butter from Bath and Body Works. Also, if he can handle latex, apply thick layers of the Cracked Heal on his hands and pull latex gloves on for overnight or use the gloves sold at BBW. It works wonders on hands. I keep it with me because my hands are constantly in water from throwing pottery on a wheel. They can become so dry they crack to the point where the skin splits. I can't handle an infection because I have lupus (SLE) and Sjogren's disease (autoimmune diseases that hosed my immune system).
In addition to wrapping my hands as well as my husband's hands in the Cracked Heel (Cracked Heal) from BBW's with the gloves, I also add it to my and my husband's feet with thick socks to help soften our feet.
I used to have very tough feet, especially my heels because I used to go barefoot all the time . I could walk through corn fields, tobacco fields, and even on the levees in Louisiana where they spread crushed shell to give cars (vehicles in general) traction to use the levees when the roads are washed out. I could walk on them without shoes without problems at all. Today, that's a different story...
If I walk on hard surfaces like rocks and shell, I have to wear shoes because my feet no longer after the calluses they had once upon a time. My husband's feet are more tender now than they have ever been because I use Cracked Heal on his feet too as well as his hands. He worked construction in telecommunications and I've worked in about everything over the years including waitressing, on a shrimp trawler, scraping barnacles off ship hulls beneath the water line, repairing, setting, & pulling nets as well as crab pots, cropping, handing, and stringing tobacco as well as tossing up to put the sticks filled with tobacco in barns. I've done it all and my hands showed it once upon a time. Now, they are baby smooth even though I use a clay that has a fairly heavy consistency of grog in it.
Try Cracked Heal from BBW and wear gloves & socks for about a month. You'll see a major difference. It will be like night and day.
BTW, if you live near an outlet store for BBW, you can get Cracked Heal for next to nothing although it's not that expensive in the retail stores either. It's only about $12.50 for a jar and a little goes a long way even when applying it thick, which you need to do so the emollients soak in well to soften the skin. It's one of the quickest, cheapest, and easiest ways to get soft hands and soft feet as well as soft elbows of any product I've tried including department store brands (too thin & not enough of the good stuff in the product), expensive brands (so expensive yet so little product and it doesn't do what it claims in a third of the time Cracked Heal works), and it's easy to get your hands on than Avon or other companies you have to order from and then if you are like me, you could very well be allergic to the ingredients. I can't use Avon products at all because they add something in the ingredients that cause me to have an allergic reaction so I've stayed away from Avon for years. I do occasionally try a sample product to find out if they've taken out what I'm allergic to every so many years but the end result is always the same. At least with BBW, I can return a product if it doesn't work but so far, I haven't found anything that doesn't work. All I have to do is stay away from the wood-infused products because I'm allergic to things like Pine, Sandlewood, etc... Other than that, it's all good. I haven't found anything yet at BBW (again with exception to wood-infused items that go on the body directly or in bath water like the bath oils) that I can't use and that doesn't do a great job for me and for my husband as well as my kids. My girls grew up on Bath & Body Works.
BTW, don't worry about the scent of Cracked Heal. It doesn't have a perfumed female scent. Your other-half will do well with it. If he washes his hands frequently, have him apply a little bit to his hands afterward to help the process along but remember it does best to spend a full night over the course of about a month with gloves or footies/socks on with the Cracked Heal applied well to soak into the skin softening it while he sleeps.
