The top of the foot becomes especially itchy after taking off shoes.

Itching on the top of the foot after removing shoes may be caused by physiological factors, or pathological conditions such as allergic dermatitis and asteatotic eczema. Treatment can be achieved through general care or medication. Specific details are as follows:

I. Physiological Factors

If foot skin care is neglected or if tight shoes and socks are worn, the skin on the top of the foot may become excessively dry, leading to the above symptoms. It is recommended to wear loose, comfortable shoes and socks, and avoid prolonged walking.

II. Pathological Factors

1. Allergic Dermatitis

This typically occurs after exposure to various allergens, triggering an abnormal immune response in the body, resulting in swelling, stinging, itching, and other symptoms. Medications such as hydrocortisone butyrate cream or triamcinolone acetonide acetic acid cream may be used under medical guidance.

2. Asteatotic Eczema

This condition is primarily associated with reduced sebum secretion on the skin surface, which may lead to dryness, itching, and cracking of the skin. Under a doctor's supervision, topical treatments such as desonide cream or tacrolimus ointment can be applied.

In addition to the above causes, similar symptoms may also result from conditions such as palmoplantar pustulosis, athlete’s foot (tinea pedis), or psoriasis. Avoid scratching with hands and maintain cleanliness of the affected area.
