There are several causes of blisters.
'Blisters are usually caused by injury to the skin from heat or from friction, which create a tear between the epidermis—the upper layer of the skin—and the layers beneath.
Short periods of intense rubbing can cause a blister, but any rubbing of the skin at all can cause a blister if it is continued for long enough. Blisters form more easily on moist skin than on dry or soaked skin, and are more common in warm conditions.
Sometimes, the skin can blister when it comes into contact with a cosmetic, detergent, solvent or other chemical; this is known as contact dermatitis. Blisters can also develop as a result of an allergic reaction to an insect bite or sting.
There are also a number of medical conditions that cause blisters. The most common are chickenpox, herpes, impetigo, and a form of eczema called dyshidrosis. '
It would be best to consult a doctor if it does not resolve on its own in a few days.

I had this problem for about 3 years and about a month ago I was put on Flouxitine. (Prozac) and they are gone. I heard that it is a type of ezema and that comes from stress I guess that's why they went away. Hope this is of some help
Allergic reaction to bee stings and insect bites?
Hey doc, you almost said it! You did say blisters come from allergic reactions! Man, allergy to latex or polyester just won't come out of your mouth huh?
Tell this girl, your the doc. She won't believe me!
Tell her she can also get blisters from ACD. "Allergic contact dermatitis"
Because it is on the bottom of the feet, it must not be the shoes! ha ha
No way it could be that! After all her feet are only pressing down on her latex and polyester in the shoes. And you know that light contact is less reaction than a tight contact.
Girl, you need to look into if you are allergic to latex, polyester, vinyl, and the other synthetics. They will tell you you have only mild allergy to it, because they don't want you to panic. But mild is enough to cause blisters.
Tell me,,, do your feet sweat? Because allergies of this type can make your feet sweat. It doesn't hurt to be tested for allergies, or pull out your insoles and apply 2 layers of masking tape to them and put them back in.
Or just use all leather shoes. Don't be afraid.
Blisters can also develop as a result of an allergic reaction to an insect bite or sting.
Oh yeah doc, she was bitten or stung on both feet and hands, but no place else.
