I have used this high-heel shoe stretcher on two pairs of shoes, one leather and one suede, with great success.  Two to three days were needed to widen the areas that I needed.  Two small setbacks, however--the attached and removable metal pieces used to stretch specific areas of the shoe are difficult to remove.  Once you grip the removable piece, it twists off.  It just wasn't as easy as it sounds.  Secondly, the back part of the shoe stretched also, as the entire wooden stretcher is wide.  I'm still glad that I purchased this product, though.  Prompt delivery, too.
