Introduction
The term "foot sole" generally refers to the bottom of the foot. In most cases, calluses on the sole are not caused by problems in a specific internal organ, but rather by excessive friction, ill-fitting shoes, lack of essential nutrients, poor blood circulation, or foot deformities. Patients are advised to receive appropriate treatment as directed by a healthcare professional. It is recommended that individuals seek timely medical attention when experiencing discomfort and undergo standardized treatment under a doctor's guidance.

The sole of the foot generally refers to the plantar surface. In most cases, calluses on the soles are not caused by problems in a specific organ, but rather by excessive friction on the soles, ill-fitting shoes, lack of essential nutrients, poor blood circulation, or foot deformities. Patients are advised to follow medical guidance for symptomatic treatment. Specific causes are analyzed as follows:

1. Excessive Friction on the Soles

If patients frequently engage in prolonged walking, running, or similar activities, the epidermal layer of the sole may separate from the dermal layer. Over time, this can gradually lead to callus formation. Soaking the feet regularly can effectively soften the stratum corneum and help eliminate calluses.

2. Ill-Fitting Shoes

If a patient's shoes are too small, they may tightly compress the feet, increasing friction between the soles and the shoes, which over time can lead to calluses. Shoes that are too large can also increase skin abrasion on the feet and result in callus formation. It is recommended that patients choose properly fitting footwear and, under a doctor’s guidance, use exfoliating scrubs to remove dead skin.

3. Nutrient Deficiency

Picky eating or restrictive dieting may lead to insufficient intake of essential nutrients, failing to meet the body's needs for growth and development. For example, a deficiency in vitamin B may cause skin disorders on the feet, such as dryness and cracking. Some individuals may develop thickened stratum corneum, presenting as calluses on the soles. Patients are advised to supplement adequate vitamins and consume more vegetables and fruits to increase vitamin intake and reduce various skin issues on the feet.

4. Poor Blood Circulation

In some elderly individuals, impaired blood circulation leads to inadequate nutrient supply to the skin, resulting in rough skin texture. Treatment may include medications such as enteric-coated aspirin tablets or nimodipine tablets, as directed by a physician. Regular physical activity is also recommended to help improve circulation.

5. Foot Deformities

Congenital foot deformities, such as heel spurs or hallux valgus (bunion), may cause excessive pressure and repeated friction on the feet during long-term walking, leading to callus formation on the soles. Under medical supervision, topical medications such as tretinoin cream or salicylic acid ointment may be used to help exfoliate the thickened skin.

Patients are advised to seek timely medical attention when experiencing discomfort and to undergo standardized treatment under professional guidance to promote recovery.

How to relieve foot cramps
When experiencing foot cramps, symptoms can generally be relieved through methods such as stretching the foot muscles, pressing on the cramped area, applying heat to the affected region, moving the leg joints, and replenishing fluids and electrolytes. After sitting down, straighten the leg with the cramp and use your hand to grasp the toes, slowly pulling them toward your body and holding this position for 10–15 seconds. This movement directly stretches the cramped muscles in the sole of the foot, helping to relax the tense muscle fibers.
