...invention (beside the iPod).

These shoe stretchers are the first pair of stretchers that I have ever owned, so with that being said I don't have much to compare them to, but based on my experience with these I am a happy person.

While these shoe stretchers are not specifically for high-heels (stilettos), I was still able to put them inside my stilettos and stretch out the areas nearest the toe area.  I would leave the stretchers in the shoes for about 2 days.  Within 2 days, my leather shoes would be stretched further enough that they did not irritate my pinky toe.  Because of these stretchers I am able to wear my stilettos for hours longer than I used to because my pinky toe is no longer in jeopardy of getting a bunion or corn.
