The heels roughen and crack more easily than the rest of the body for a simple reason: the soles have no sebaceous glands, while load and friction are constant. The good news — in most cases this is fixed at home with the "soak and seal" method. Let us work out the working routine and the signs of when cracks should be shown to a doctor.
The heels get dry because the soles have no sebaceous glands, plus pressure, friction and dry air. The routine: a short warm shower → gentle exfoliation of the roughened skin → a cream with urea 10–25%, AHA or salicylic acid on damp skin → at night petroleum jelly + socks; on the cracks — a "liquid bandage". Do not cut the skin with a blade or rub open cracks. Persistent/deep cracks occur with diabetes, eczema, psoriasis — see a doctor.
01Why the heels crack
The soles have no sebaceous glands, so the skin here is especially prone to dryness. Add pressure and friction when walking, open footwear, walking barefoot, a hot shower and harsh soap — and the skin roughens, calluses form, and then cracks (fissures). With age the skin loses elasticity, and the risk grows. Deep cracks are painful and can become a gateway for infection, so it is not worth letting them go.
02The "soak and seal" method
The basic approach: a short warm (not hot) shower or a foot bath for a few minutes, to soften the skin → gently remove the roughened skin with a pumice stone or file (without fanaticism) → within 5 minutes, while the skin is damp, apply a cream with urea 10–25%, AHA or salicylic acid. At night — a layer of petroleum jelly and cotton socks, to seal in moisture. There is no need to soak the feet for long — that, on the contrary, weakens the barrier.
03Protection and footwear
So that cracks heal and do not return: during the day you can apply a "liquid bandage" over the cracks — it creates a protective barrier, reduces pain and keeps out infection. Wear closed, well-fitting footwear; avoid flip-flops and worn-down shoes if the heels are already cracked. Do not cut the roughened skin with a blade — it is easy to injure yourself and introduce infection. Use a pumice stone gently and only on softened skin.
- Cutting calluses with a blade/razor. A risk of injuring yourself and introducing infection.
- Rubbing open cracks with a pumice stone. Exfoliation — only on intact roughened skin.
- Soaking the feet for long. Prolonged soaking weakens the barrier and increases dryness.
- A hot shower and harsh soap. Wash off lipids, the skin roughens faster.
- Ignoring deep/non-healing cracks. They can occur with diabetes, eczema, psoriasis — see a doctor.

05Common questions
Can I just cut off the roughened skin?
No, with a blade and razor it is dangerous: it is easy to injure the skin and introduce infection. Safer to soften it in the shower and gently work it with a pumice stone, then hydrate.
Why doesn't cream help?
Often there is not enough exfoliation and occlusion. The combination works: remove the roughened skin + a cream with urea/acid on damp skin + petroleum jelly at night under socks.
When to see a doctor?
If the cracks are deep, painful, bleed, do not heal or are inflamed — and also with diabetes, eczema, psoriasis. That is a reason to see a dermatologist.
