The unique gel arch works by taking the pressure off of the ball of your foot therefore making heels more comfortable. They have a sticky back so they stay in place well but not so much that they can't be removed and placed in to other shoes. And they are nice and thin so they don't crowd your foot in your shoes.
I think my favorite part is that they're clear so they blend in with the bottom of any shoe and no one can tell that you're wearing them
