Why didn't I think of that?

I have the "why didn't I think of that?" feeling when I see a product that I think is a good idea. This idea is temporary, compact flats to wear when your heels have become unbearable.

Fast Flats.  Clever!

I have had many occasions when I wish I could switch into a flat, even if it is just for the cab ride home. (If I'm driving I just go barefoot.)

While searching for images of Fast Flats I came upon this similar product...

FootzyRolls.

These come in a variety of colors and come with two carrying bags, one for the Footzyrolls and one for your heels.

I don't go out in heels much anymore, but I would have really appreciated these in my younger, party going, high heel-wearing days.
