Quick summary: Cracked heels affect nearly 48% of the population yet remain one of the least studied conditions in modern medicine, with women, older adults, and people with diabetes at greatest risk. Most cases can be managed through daily moisturising, gentle exfoliation, and supportive footwear, though severe or persistent fissures may require clinical intervention including laser therapy or keratolytic agents. The growing global treatment market, projected to reach USD 2.3 billion by 2033, underscores the need for stronger clinical guidelines and greater investment in preventive foot care, particularly for high-risk groups.
Cracked heels affect close to half the global population, yet they are one of the least researched conditions in dermatology and foot care. A review published in the International Journal of Aesthetic Plastic Surgery draws attention to just how widespread and poorly understood this everyday problem is, calling for better clinical guidance and preventive care.
The condition, medically known as heel fissure or xerosis of the foot, begins when the skin’s outer layer loses its ability to retain moisture. The skin becomes hard and flaky, eventually breaking into painful cracks that can bleed and become infected if left untreated.
Women are more commonly affected than men, with a prevalence of 58.4% compared to 33.3%. Housewives and farmers are among those most at risk, owing to prolonged standing and physical strain on the feet. The study notes that despite its prevalence, cracked heel treatment remains an underexplored area in modern medical literature.
The causes of cracked heels are broad. Walking barefoot on hard surfaces, wearing open-backed sandals, obesity, pregnancy, and prolonged standing are all contributing factors. Systemic conditions including diabetes, hypothyroidism, and peripheral vascular disease also raise the risk significantly, as do nutritional deficiencies in vitamins A, C, D, E, and zinc.
Older adults are particularly vulnerable, as ageing skin produces fewer natural oils and becomes less elastic over time. For people with diabetes, the stakes are even higher: cracked heels can progress to open wounds and serious foot complications, making regular monitoring essential.
Most mild cases respond well to home care. Applying a high urea-based moisturiser daily, using a pumice stone to remove dead skin, staying well hydrated, and wearing supportive closed footwear are among the most effective preventive habits. Natural remedies including coconut oil, honey, paraffin wax, and neem and turmeric paste have also been shown to help, particularly when used consistently over two weeks.
For more persistent or severe cases, clinical options include keratolytic agents, liquid bandages, and debridement. The review also highlights emerging treatments: low-level laser therapy has shown promise in reducing heel fissure pain and promoting wound healing, while trichloroacetic acid has demonstrated improvement in deep fissures following a single application.
The cracked heels treatment market was valued at approximately USD 1.4 billion in 2024 and is projected to reach USD 2.3 billion by 2033, driven by greater consumer awareness and an ageing global population. The irony, as the authors point out, is that commercial interest is outpacing the scientific evidence base.
The authors recommend that anyone presenting with cracked heels also be assessed for diabetes through blood sugar testing, as the condition can be an early indicator of diabetic foot involvement.
