People can develop all kinds of allergic reactions to any substance. Some of these allergies might sound strange such as shoe allergies but for those who are suffering from this allergy, it can be very inconvenient.
Shoe allergy causes
Shoe allergy is a kind of contact dermatitis on the feet but it is different from foot allergy. Shoe allergies are common among children. It can be developed by wearing shoes which can keep the feet confined and covered most of the time. There are several shoe-based irritants which can cause shoe allergy. Some of the irritants are paratertiary butylphenol and colophony which are ingredients of the glue used in shoes. Other irritants include dyes, metal components (nickel sulfate, rubber chemicals (mercaptobenzathiazole) and leather components (potassium bichromate). These irritants react when the feet sweats.
The symptoms of shoe allergies include allergic eczema flare-up which can occur on one or both sides of the foot, skin lacerations, pruritus or severe itching and flaking of the toes and upper surface of the feet. Other symptoms are blisters, foot pain, fissuring and swelling of the feet. The soles and the areas between the toes are not affected by shoe allergy because they are thicker.
The diagnosis of shoe allergy can be difficult sometimes because the signs and symptoms of shoe allergies can be related to other diseases such as atopic eczema. Diagnosis starts with examination of the feet. The location and characteristics of the dermatitis and inflammation are key indicators for the diagnosis of shoe allergy. A patch test can be done for a more accurate diagnosis. A skin patch test is done by cutting parts of the shoe which covers the areas of the feet which are affected. The layers of shoe part should be separated after which each layer should be dampened. The doctor will then attach the layer on the upper arm using a specialized patch tape. After a certain amount of the time, the shoe layers will be removed and the skin will be checked for allergic reactions such as reddening of the skin.

Prevention of shoe allergies starts with good hygiene and regular foot care. People who are prone to shoe allergies should take preventive measures to control sweating of their feet.
