I wish I had thought of these.  They do just what they say they do.  For people like me with less than perfect flexibility or with joint problems, these are of great help.  They are relatively easy to insert although, if your eyelets are small, it may be a little more difficult.  If your shoes are cut high, you may need to omit the top eyelets in order to easily slide your shoes on.  A shoehorn may also be helpful.

 I hope these don't seem like negatives because these seem trivial compared to how nice they look,  how well they hold your foot in your shoe, how much easier it is to put on my shoes everyday.
