I just had another pair of shoes done. This time I had my cobbler Topy my C&J Edgwares:
As you can see, you can't really tell a shoe has been Topied from the side.
My cobbler was originally going to dye the entire sole black to match the Topy, but I told him to leave the rest of the un-topied sole alone and not to dye it. Looks better this way I think instead of having the entire sole dyed black.
