What causes rough skin on the soles of the feet?

Causes of rough skin on the soles of the feet: 1. Dry, dehydrated skin is a common cause of rough soles. This may result from frequent use of alkaline chemicals such as soap and detergent, or prolonged exposure to dry environments, leading to moisture loss in the skin. 2. Thickening of the stratum corneum (outer layer of skin) is another significant factor. This often occurs due to prolonged walking, wearing high heels, or tight-fitting shoes, which place excessive friction and pressure on the soles, causing the skin to thicken. 3. Poor nutrition, insufficient moisturization, and underlying skin conditions such as asteatotic dermatitis or athlete's foot may also contribute to rough skin on the soles. To improve rough skin on the soles of the feet, it is recommended to keep the skin moisturized, maintain a balanced diet, wear comfortable footwear, and perform regular foot care.
