Blisters occur when areas of the foot rub against shoes. Fluid fills up a space between layers of skin to protect the area, like a small balloon. People with diabetes may not be able recognize the painful event due to a condition called neuropathy. Specialized care is required to treat their blisters and burns.
Causes of Foot Blisters
Form as a result of heat, moisture and friction.
Friction forces caused by inappropriate footwear.
Form as a result of fungal infections of the skin, allergic reactions or burns.

Appearance of Foot Blisters
Sometimes these blisters “pop” by themselves and can become infected. Watch out for redness or leaking yellow liquid, and for red lines near the blister. These are symptoms that require medical attention. If the blister has not “popped,” then leave it alone. Most of the time it will reabsorb and heal on its own.
