I recently bought my first couple pairs of premium Drivers, both made from Gucci (links below). The black one, is made of really thin, delicate leather (almost like driving gloves). I don't know much about shoe care (and even less at the time of purchase), so I bought shoe trees from Bloomingdales and the sales associate put in a pair that was probably a size to big and it stretched them out so that it feels loose in the heel. Is there any way to shrink them without damaging the leather? I've read to dampen them and then put them in the window to dry, and then put on conditioner, but I am afraid what that will do. Are there any alternatives?
Separately, does anyone have any good leather shoe conditioners to recommend? I can't figure out from other threads if it matters which brand you use, the versions that pop up on amazon don't seem to be shoe specific, and I'm not sure if that matters (especially for the black pair, which is extremely soft as is)
thanks in advance
