No, i found out that it was from my feet being irritated by different fabrics of my shoes. thanks for replying.
Are the circles larger than a pencil eraser in diameter? If so, you should see a dermatologist to rule out skin cancer.
A dermatologist also might have suggestions on what you might try for them if they are something else. Marketing of products is a common practice to doctors and I think dermatologists are no exceptions, so they are likely up on the latest innovations for things like this.
