Can older shoes that have developed the inevitable creases in their uppers--particularly on the instep where most shoes bend when we take a step--be rehabilitated insofar as removal, or smoothing out, of these creases? I have several pairs of older, very comfortable, and, to my eye stylish, shoes that I'd like to refurbish. A couple of them are A-E and thus can go back to the factory for the A-E recrafting service. The others are Bally and Ferragamo (I'm not yet in the Edward Green, C & J, Vass, etc., league!). I try to take good care of my shoes, and there are no cracks or tears in the leather, just creases from wear. I don't expect that I can do this myself, but can shoemakers or shoe-renewers do something with these creases that helps shoes look somewhat new again?
