These high heel shoe stretchers are the first I've owned - as they are specifically for high heels.  And, they work perfect!  The quality of the stretchers if top notch!  And they fit amazingly inside my high heels.  All really helpful as well as my left foot is slightly wider than my right and the add-ons for the tow area is very necessary.  Will purchase another set in order to stretch multiple pairs of shoes at the same time.  I wear 7-1/2 and my heels range from 3 to 5 inches.
