Why does the foot seam crack so easily?

The most common situation of toe joint cracking is tinea pedis, which is a common skin disease caused by fungal infection. When the weather is hot, or in winter, when the feet are sweaty and airtight, there will be obvious cracking and itching. Not all toe cracks are directly related to fungal infection. Some patients have cracked toes, which may be caused by other diseases, such as skin allergies such as eczema or contact dermatitis. If the time is long, the local skin will appear obvious hypertrophy and hyperplasia, and there will also be obvious cracking. Other patients may have obvious skin cracking at the toe seam and heel because the local skin is very dry, which is more common in the elderly.
