Introduction
In general, friction on the sole of the foot may be caused by ill-fitting shoes, abnormal gait, foot structural issues, eczema, scleroderma, or other reasons.
If friction on the sole is accompanied by other abnormal symptoms, it is recommended to consult a doctor or podiatrist for evaluation. In daily life, one should also ensure adequate rest and avoid excessive fatigue. During dry seasons, it is advisable to reduce bathing frequency. Showers are preferred over baths during routine hygiene.
Generally, soreness or friction on the sole of the foot may be caused by ill-fitting shoes, abnormal gait, structural foot problems, eczema, scleroderma, and other reasons. Patients are advised to visit a hospital for a thorough examination to determine the exact cause and receive appropriate treatment. Specific analysis is as follows:
1. Ill-fitting shoes: Wearing shoes that do not fit properly—such as those that are too tight, too narrow, or lack sufficient cushioning—can increase friction between the sole of the foot and the shoe's insole. It is recommended to wear properly fitting shoes to avoid adverse effects on the feet.
2. Abnormal gait: Incorrect walking posture, such as intoeing or outtoeing, may place extra pressure on certain areas of the sole, leading to soreness or friction. For mild cases, maintaining an upright posture while walking is important. Under medical guidance, manual correction techniques such as massage and stretching exercises may also help correct the condition.
3. Foot structure problems: Congenital structural abnormalities of the foot, such as flat feet or high arches, can result in uneven pressure distribution on the sole, causing excessive wear. In such cases, orthotic devices are typically required to correct the issue.
4. Eczema: This condition is a skin inflammation involving the superficial dermis, triggered by various internal and external factors. Clinically, acute-phase lesions are primarily characterized by papulovesicular eruptions with a tendency to exude fluid. After blisters rupture, the skin may become dry or develop excessive keratinization, increasing susceptibility to abrasion. Symptoms can be improved under medical supervision using topical medications such as anti-inflammatory and antifungal ointments, Qingpeng ointment, or boric acid solution.
5. Scleroderma: A connective tissue disorder characterized by localized or widespread hardening of the skin and progressive fibrosis of internal organs, often associated with genetic factors and immune-mediated vascular damage. Symptoms include edematous red patches, skin atrophy, hair loss, and joint pain. If thickened stratum corneum develops on the soles, it may increase friction and wear. Localized helium-neon laser irradiation, administered under medical guidance, may provide therapeutic benefits.
If soreness on the sole is accompanied by pain, redness, swelling, fever, or other unusual symptoms, or if the condition persists and interferes with daily life, it is advisable to consult a physician or podiatrist for evaluation. In daily life, adequate rest should be taken to avoid overexertion. During dry seasons, bathing frequency should be reduced. Showering is preferred over soaking baths.
