Heel Fissures: Why They Happen, Why They Hurt, and When to Get Them Checked
Heel fissures — those painful cracks that form around the edges of the heel — are incredibly common. For some people they’re just a cosmetic annoyance, but for others they can split deeply enough to make walking uncomfortable, catch on socks, or even bleed.
What surprises most people is how quickly they can go from “a bit of dry skin” to “I can feel every step.” Understanding why they form is the first step toward keeping them under control.
What Are Heel Fissures
Heel fissures are cracks that develop in the thick, dry skin around the heel. They often start as shallow splits but can deepen over time, especially when the skin is under pressure.
Common features include:
Dry, thickened skin around the heel
Cracks that may be shallow or deep
Pain when walking or standing
Occasional bleeding if the fissure splits
Rough skin that catches on socks or bedding
They’re not usually dangerous, but they can be very uncomfortable.
Why Do Heel Fissures Happen?
Heel fissures form when the skin becomes dry, thick, and less flexible. When pressure is applied — especially during walking — the skin can split.
Common contributing factors include:
Dry skin
Often worse in winter or with certain skin conditions.Callus build‑up
Thickened skin loses elasticity and cracks more easily.Open‑back footwear
Allows the heel to expand sideways, increasing splitting.Prolonged standing
More pressure on the heel pad.Foot shape or gait
Certain loading patterns increase heel pressure.Medical conditions
Diabetes, eczema, psoriasis, and thyroid issues can all contribute.
Even small changes in skin hydration or pressure can make a big difference
Are Heel Fissures Serious?
Most heel fissures are not serious, but they can become problematic if:
They’re painful
They split deeply
They bleed
They show signs of infection
You have diabetes or reduced sensation
They keep returning despite your best efforts
Deep fissures can act like small wounds, so it’s important to keep an eye on them.
Why Do Heel Fissures Keep Coming Back?
Heel fissures often return because the underlying pressure or dryness hasn’t changed.
Common reasons include:
Persistent callus build‑up
Footwear that exposes the heel
Standing for long periods
Skin that naturally dries out quickly
Repeated pressure from walking patterns
Managing the cause is just as important as managing the symptoms.
When Should You Get Heel Fissures Checked?
It’s worth booking an assessment if:
The fissures are painful or deep
They’re bleeding or showing signs of infection
They keep returning
You’re unsure whether it’s just dry skin or something else
You have diabetes or circulation concerns
They’re affecting walking or footwear
A podiatry assessment can help identify what’s contributing and what’s keeping them going.
A Final Reassurance
Heel fissures are incredibly common, and they’re nothing to be embarrassed about. They’re simply a sign that the skin around your heel is under pressure or lacking moisture. Understanding why they’re happening is the key to longer‑lasting comfort.
If heel fissures are starting to get in the way of your day, a podiatry assessment can help you understand what’s going on and what steps will make the biggest difference
