They last for a very long time!
I love this product.  I put them on my gucci loafers and walked miles along the Las Vegas strip and at the end of the day, I thought that the protector for sure have gotten torn up and I wanted to see the damage I did to my soles.  There was absolutely no damage and even though it looked black on the bottoms, they were not torn and the protector was still in one solid piece.  Just amazing!
