Your feet take a beating. Every single day, they haul your entire body weight across hard hardwood floors, concrete sidewalks, and maybe those stylish but completely unforgiving shoes you wore to the wedding last weekend. Eventually, the skin gives up. It splits. It's called heel fissures in medical speak, but most of us just call it a painful mess that catches on our socks. If you're looking for what to do about a cracked heel, you've probably already realized that a quick swipe of lotion isn't going to cut it.
It hurts. Walking feels like stepping on tiny paper cuts. Honestly, it's more than just a cosmetic thing; it’s a structural failure of your skin. When the skin around your heels becomes dry and thick—a condition known as a callus—it loses its elasticity. Add the pressure of walking, and the skin literally snaps.

Why your heels are actually splitting
Let's get real about the "why" before we fix it. Most people think they just need more water. Sure, hydration matters, but it's rarely the only culprit. Open-back shoes are a huge offender. When you wear flip-flops or mules, the fat pad under your heel expands sideways because there’s no shoe wall to hold it in place. That expansion puts immense mechanical stress on the dry skin at the edge.
Then there's the medical side. According to the American Academy of Dermatology (AAD), things like diabetes or hypothyroidism can significantly change how your skin retains moisture. If you have athlete's foot (tinea pedis), that fungus can mimic simple dry skin, making your heels look powdery and cracked when they actually need an antifungal, not just a moisturizer.
The urea secret (and why your current lotion is failing)
You probably have a bottle of "intensive repair" lotion in your bathroom right now. It might have a cute scent. It might feel greasy. But if it doesn't have a high concentration of Urea, you're basically just painting over a crumbling wall.
Urea is a keratolytic. That’s a fancy way of saying it breaks down the "glue" holding dead skin cells together. While standard lotions just sit on top of the callus, urea gets in there and dissolves the thickened mess. For serious cracks, you want something in the 20% to 40% range. Brands like Eucerin or PurSources make these high-potency creams. If you use a 40% urea cream, be prepared—it’s powerful stuff. It will make the dead skin turn almost mushy over a few days so you can gently buff it away.
Mechanical removal: Don't go overboard
Stop using those "cheese grater" style foot files. Seriously.

I know it’s tempting to just saw off the dead skin, but your body is smarter than you think. If you cause trauma to the heel by filing too aggressively, the skin responds by building an even thicker callus to protect itself. It's a vicious cycle. Instead, use a high-quality pumice stone or a fine-grit diamond file.
- The Soak: Ten minutes in lukewarm water. Not hot. Hot water strips oils.
- The Buff: Gentle, circular motions on the edges of the crack.
- The Seal: Immediately apply your treatment while the skin is still slightly damp.
The "Sling" method for deep fissures
If your cracks are deep enough to bleed, you need to treat them like a wound. Because they are. When a crack is deep, it's an open door for bacteria like Staphylococcus aureus to enter the bloodstream. This is especially dangerous for anyone with poor circulation.
Try the "Sling" or "Liquid Bandage" trick. After cleaning the area, you can use a liquid skin bandage (like New-Skin) to seal the crack. This holds the edges together so the skin can heal from the bottom up without being pulled apart every time you take a step. It stings like crazy for five seconds, but it works.
Another pro tip from podiatrists? Hydrocolloid bandages. These are the "blister bandaids" you see at the drugstore. They create a moist environment that speeds up cellular repair significantly more than letting the crack "air out."
The overnight occlusion trick
This is the nuclear option for what to do about a cracked heel when you have a big event coming up. It’s gross, it’s sweaty, and it’s incredibly effective.
- Slather your feet in a thick layer of 20% Urea cream or plain white petrolatum (Vaseline).
- Wrap your heels in plastic wrap (Saran wrap).
- Pull a pair of clean cotton socks over the top.
- Sleep.
By morning, the skin will be significantly softer. The plastic wrap prevents the moisture from evaporating or being absorbed by your socks. Just don't do this every single night, or you'll end up with "macerated" skin—that white, soggy look you get after being in the bathtub too long—which can actually weaken the skin structure.
When it’s more than just dry skin
If you've tried the urea, the filing, and the socks, and nothing is changing, look at your shoes. Are you wearing "dead" sneakers? Most athletic shoes lose their shock absorption after 300-500 miles. When the foam dies, your heel takes the full force of every step, causing the skin to thicken in self-defense.

Also, check your gait. People who "strike" heavily on their heels or have flat feet often deal with chronic cracking because of how the weight is distributed. Sometimes a simple $20 orthopedic insert can do more for your heels than $200 worth of skin creams.
Specific product recommendations that actually work
- Flexitol Heel Balm: This is the gold standard for many. It has a high urea content mixed with lanolin.
- Kerasal Intensive Foot Repair: This uses salicylic acid to exfoliate and white petrolatum to hydrate. It’s greasy, so wear socks.
- O'Keeffe's Healthy Feet: Better for maintenance than for fixing deep, bleeding cracks. It contains a lot of paraffin, which creates a great barrier.
Actionable steps for immediate relief
Don't just read this and go back to your day. If your heels are hurting right now, here is the immediate game plan to get them back under control.
- Seal the deep ones: If there is any redness or "raw" looking skin inside the crack, apply an antibiotic ointment and a liquid bandage. Do not file skin that is currently bleeding or inflamed.
- Switch to closed-back shoes: Put the flip-flops away for at least two weeks. Your skin needs a break from the constant expansion and contraction of the heel pad.
- Check your soap: Most bar soaps are highly alkaline and strip the natural fats (ceramides) from your skin. Switch to a "soap-free" cleanser like CeraVe or Cetaphil for your shower routine.
- Hydrate from within: It’s a cliché because it’s true. If your internal hydration is low, your extremities—like your heels—are the first place the body "steals" water from to keep your organs functioning.
- Schedule a "maintenance" day: Once a week, do the soak and gentle file. Don't wait until it hurts again.
If you see signs of infection—red streaks, warmth, or pus—skip the home remedies and see a doctor or a podiatrist. For everyone else, consistency is the only thing that works. Your skin didn't crack overnight, and it won't perfectly seal overnight either. Stick to the urea and the barrier creams, and you'll be able to walk without wincing in about seven to ten days.
