Cracked heels
back to main page
Rhagades on the heels are linear cracks in the excessively hyperkeratotic epidermis, developing most commonly on the posterior and lateral surfaces of the heel. The lesions develop as a result of a combination of skin dryness, loss of elasticity, and mechanical stress associated with standing and walking. Initially, they appear as shallow fissures within the stratum corneum. In a more advanced stage, they reach the viable layers of the epidermis or the dermis, causing pain, bleeding, and an increased susceptibility to infection. Rhagades may be a local skin care issue, but they can also accompany dermatological, metabolic, neurological, and vascular diseases. Assessing the depth of the cracks, blood supply status, protective sensation, and the presence of inflammation allows for establishing a safe method of treatment.
Cracked heels - where do they come from
The direct cause of rhagades is exceeding the mechanical strength of the epidermis. During weight-bearing on the foot, the heel fat pad flattens and displaces laterally. Skin that maintains adequate hydration and elasticity adapts to this movement. Dry, stiff skin covered with hyperkeratosis—that is, an excessively thickened stratum corneum—reacts by forming fissures.
The main contributing factors include:
- skin xerosis, meaning excessive dryness associated with a reduced amount of lipids and natural moisturizing factor in the stratum corneum;
- prolonged standing, intensive walking, and working on hard surfaces;
- open-heeled footwear, which limits lateral stabilization of the fat pad;
- excess body weight, increasing pressure on the posterior part of the foot;
- gait biomechanics disorders, foot deformities, and abnormal load distribution;
- frequent foot soaking, hot baths, and the use of strongly degreasing cleansers;
- mature age, which is accompanied by a decrease in epidermal lipid content and slower renewal of the skin barrier;
- a low-humidity climate, indoor heating, and seasonal skin dryness.
Rhagades can co-occur with atopic dermatitis, psoriasis, palmoplantar keratoderma, ichthyosis, and tinea pedis. An increased predisposition is also observed in diabetes, hypothyroidism, chronic kidney disease, peripheral neuropathies, and circulatory disorders of the lower extremities. In such situations, treatment includes both local management of the skin and control of the underlying disease.
Heel fissures - what do deep cracks indicate
The depth of the rhagade reflects the degree of damage to the epidermal barrier. Shallow, dry fissures mainly involve the stratum corneum. Deep cracks reach living layers, which is why they may cause burning, pain during weight-bearing, pinpoint bleeding, or exudate. Every step stretches the edges of the fissure and perpetuates microtrauma, which slows healing.
Deep rhagades may indicate:
- advanced hyperkeratosis and a significant loss of skin elasticity;
- long-term mechanical overload of the heel;
- improper care based on aggressive abrasion of the epidermis;
- dermatosis involving impaired keratinization;
- hyperkeratotic tinea pedis, especially with diffuse scaling of the sole;
- neuropathy, when extensive lesions are accompanied by reduced pain sensation;
- limb ischemia, particularly with cold, pale, or cyanotic skin and slow healing;
- metabolic disorders affecting skin hydration, regeneration, and immunity.
Specialist assessment includes the appearance of the edges of the rhagade, callus thickness, signs of bleeding, exudate, and infection, as well as the distribution of lesions on both feet. In individuals with diabetes, examination of protective sensation, pulses in the foot arteries, and other signs of ischemia is indicated. A suspected fungal infection may require mycological testing, whereas a clinical presentation typical of psoriasis, eczema, or keratoderma constitutes an indication for a dermatological consultation.
Rhagades on the heels - when can they be dangerous
A crack disrupts the continuity of the skin barrier and creates a portal of entry for bacteria and fungi. Lesions that are bleeding, oozing, purulent, severely painful, or surrounded by redness, swelling, and increased skin temperature require special attention. Spreading erythema, increasing pain, fever, or chills may indicate the development of a soft tissue infection and require urgent medical evaluation.
Groups at increased risk of complications include individuals with:
- diabetes, especially with concomitant neuropathy;
- atherosclerosis of the lower limb arteries and other causes of ischemia;
- chronic edema and venous insufficiency;
- reduced immunity;
- advanced kidney disease;
- impaired wound healing;
- limited ability to independently inspect their feet.
In neuropathy, pain may remain mild despite significant tissue damage. A rhagade, subcutaneous hemorrhage, or callus in a person with diabetes is considered a pre-ulcerative lesion. International guidelines on the diabetic foot recommend their prompt management by an appropriately trained specialist. Persistent pressure can lead to ulceration, while concomitant ischemia increases the risk of prolonged healing and necrosis.
Blackening of tissues, cyanosis of the toes, marked coldness of the foot, rest pain, and sudden deterioration in the wound's appearance also require urgent consultation. These symptoms may indicate a significant impairment of perfusion, that is, blood flow to the tissues.
Rhagades on heels - home care
Home care supports the restoration of the epidermal barrier, limits the buildup of hyperkeratosis, and reduces tension acting on the edges of the fissure. The foundation is the regular application of an emollient preparation. The emollient replenishes lipids, limits transepidermal water loss, and improves the elasticity of the stratum corneum.
The key principles include:
- washing the feet with lukewarm water and a mild preparation with a physiological pH;
- thoroughly drying the skin, especially the spaces between the toes;
- applying cream to the heels once or twice a day;
- using preparations with urea, glycerin, petroleum jelly, ceramides, or lactic acid, tailored to the depth of the lesions;
- protecting the heel using closed, stable footwear;
- limiting walking barefoot on hard surfaces;
- adjusting insoles and footwear in the case of pressure distribution disorders;
- daily observation of the skin in individuals with diabetes or impaired sensation.
At lower concentrations, urea acts primarily as a moisturizer, while at higher concentrations it exhibits a keratolytic effect, meaning it facilitates the loosening of the excessively compacted stratum corneum. The choice of concentration depends on the condition of the skin. Deep, open rhagades may react with a burning sensation to keratolytic preparations; therefore, they require individual assessment.
Cutting calluses on one's own with a blade, intensive filing with a foot rasp, and the use of strong acids increase the risk of injury. Particular caution should be exercised by individuals with diabetes, neuropathy, circulatory disorders, and those undergoing therapy affecting blood clotting.
Podiatric treatments for rhagades
Professional therapy begins with an interview and an assessment of the skin, nails, footwear, and foot loading patterns. The podologist determines the depth of the rhagades, the presence of hyperkeratosis, signs of inflammation, and the need for a medical consultation. Mechanical debridement consists of the layered, controlled removal of excess callused epidermis using a podological scalpel and burs. The goal is to reduce the tension acting on the edges of the fissure while preserving the layer that protects living tissues.
At Ambasada Urody Clinic & Spa, the scope of procedures related to cracked heels includes:
- basic medical pedicure, intended for the treatment of physiological and mild pathological calluses, dryness, and superficial skin lesions;
- extended medical pedicure, covering larger hyperkeratoses, calluses, and initial superficial heel fissures;
- specialized cracked heel treatment, intended for deeper, painful, oozing, or bleeding rhagades, requiring a separate qualification;
- removal of calluses and hyperkeratosis, which reduces skin stiffness and localized overload;
- acid pedicure, used for minor calluses and small, superficial cracks following a prior assessment of the skin condition;
- customized pressure relief, limiting pressure and the spreading of the edges of the rhagades while walking.
After treating the lesion, antiseptic, regenerating, and epidermal barrier-supporting preparations are applied. In selected cases, the podologist may secure the edges of the crack with a dressing, relieving tape, or a preparation that creates an elastic protective layer. The frequency of visits depends on the depth of the rhagades, the rate of keratosis, comorbidities, and the effectiveness of overload reduction. A lasting effect requires combining the treatment with regular home care, appropriate footwear, and dermatological, diabetological, or vascular treatment when indicated by the clinical picture.
