My feet are very narrow but I have bunions.  I bought this for the meantime when I am stuck with bunions without option to remove them.  This handy gadget stretches loafers, boots, any shoes of leather or leather-like materials.  The spray comes with it, but I've found that it isn't necessary to use the spray on every fabric.  I stretched a pair of metallic fabric flats without it.

I recommend too because the silver circular attachments can be removed and placed elsewhere along the stretcher.  This helps you to customize the stretch you give your shoes.  Luckily enough, it also helps with customizing your shoe shape to accommodate pesky bunions.  Recommended for the health of feet everywhere.
