Shoe repair craftsmen are a vanishing small business. So It was do-it-myself desperation! It's a little tricky figuring out placement  of the buttons to use for bunions, etc. but after a little experimentation, for the style and cut of shoe it was easy to use. Works like a charm on good all- leather shoes,  and use with a good leather conditioner; I use Dr. Martens. It worked perfectly on a leather, leather-lined, low dress boot.  And results were pretty quick. Also used on a leather flat (skimmer) which has a man-made material lining, which doesn't have much give. Can only do one shoe at a time, but can adapt stretcher for either left or right shoe individually.
