There are many possible causes of itchy feet with blisters, including fungal infections, such as athlete's foot, and poorly fitting shoes that irritate the skin. An individual may also develop these symptoms because of an allergy to something that has touched his feet or that he has consumed. In some cases, a chronic skin condition may even prove to be the culprit.

One of the most common causes of itchy feet is a fungal infection. A person may have these symptoms when he develops a condition called athlete's foot, which is marked by such symptoms as itchiness; burning sensations; cracking skin; thickened, yellowing toenails; and itchy blisters. This condition is contagious and thrives when a person's feet are moist, such as when they are in overly tight shoes or sweat a good deal. A person can also contract the infection from surfaces, such as shared towels and shower floors in gyms. It is even possible to catch it from wearing an infected person's shoes.

In some cases, a person will develop foot problems because his shoes do not fit well. When a person's shoes and socks fit too tightly or are made out of an irritating material, for example, they can prevent the proper flow of air and literally rub the skin the wrong way. When this occurs over a significant period of time, blisters are often the result. Sometimes these blisters itch, but they can cause pain as well. Eventually, they may become infected and, if left untreated, can lead to even more discomfort.

It is also possible for an allergic reaction to cause itchiness and blisters. This can occur when a person is allergic to the material his shoes or socks are made of or to a substance that has touched his feet, such as a soap or lotion. In some cases, however, the person might have an allergic reaction that involves his feet after consuming a food or medication that stimulated the response. Often, discontinuing the use of the allergen helps relieve the irritation and blistering.

An individual might also develop itchy feet with blisters because of a chronic skin condition. These symptoms can be a sign of eczema, which causes inflamed itchy skin that can blister, crack, and bleed. A medical professional will usually prescribe oral or topical medications for dealing with problems are caused by a chronic skin condition.

@literally45-- Do you switch shoes every day? If not, you might be getting reinfected from your shoes. I also suggest soaking your feet in warm water with tea tree oil. If none of these work, you might be suffering from a different type of skin problem.

I've had athlete's foot for over a year now. I think I was almost cured one time but got reinfected from the gym. I took two rounds of oral anti-fungal medications. I think I'm resistant to them because they didn't get rid of the infection.

I'm doing my best to keep my feet dry. I use foot powder, I change my socks several times a day and I make sure my feet and toes are completely dry after showering. These methods have reduced blisters, cracks and flaking considerably but the itching is killing me!

I get itchy blisters on my feet every year in the beginning of the summer when I start wearing sandals. I think the skin on my feet is very soft because of wearing closed shoes throughout winter. Even the most comfortable sandal irritates my skin when it's like that.

In the past, I used to scratch the blisters or pop them because they annoyed me. But once I was talking to my doctor about this and he told me to never pop a blister. He said that the fluid inside the blister prevents it from getting infected. He said I should put a blister band-aid on it and let it heal on its own. I've stopped popping blisters since then.
