I have these bumps that look like warts under my foot and in-between my toes. what could they be?

See podiatrist: The best way to determine your condition is to have a podiatrist evaluate your foot. There are several conditions that can present themselves as "bumps". Unfortunately, more information is needed. An actual visit to the doctor is advised.

Hard to tell: Without seeing them but inspect closely and if little dark spots are present chances are its a wart.
