The feet can develop rashes and itching due to moist conditions, infectious bacteria, viruses, parasites, fungi, or other irritants. Irritants may be present in our surroundings and walking barefoot can sometimes lead to a rash or itchy feet. The foot can also develop itchiness when the skin is excessively dry. Foot rashes and itchiness are usually not a cause for concern but can sometimes indicate an underlying condition.
