CEC, you should be careful with this and pick a very good cobbler. Make sure that they use a similar dye (vegetable dye like
Nat said). I think she also mentioned that her cobbler in Fla uses vegetable dye that matches. I don't want to see your shoes ruined!
In order to get my Jade ADs even, I did a little experimenting

I used the tiniest film of water on my finger and very gently rubbed the surrounding well colored areas into the bald spots or less colored areas. Very, very gently and making sure that there wasn't a lot of color bleeding. Then I took my Meltonian spray and sprayed them up close, 2 coats. Now, you can't see any uneveness in color or bald spots at all. I'm not exactly recommending this method to you because I'm afraid something will go wrong! I guess I was letting you know what worked for me.
