Those shoes will be fine.

Watch a #$%load of youtube videos. Specifically, the "elegant oxford" about refinishing.
He has dealt with far worse, and he has a well deserved following.

I think he prefers Bick-4 leather conditioner/cleaner for not darkening leather.

As for getting the shoe back lighter, he's got a bunch of tips on that too. You could try light acetone, but watch the videos first. Nail polish remover seems to be a little more diluted if you want to start off baby steps.

Another thing I'll do is use saphir renovateur, and saphir clear cream. Applied with bounty napkin, the shoe cream will even pull out some of the darkening/pigment/dye. It is much less aggressive than acetone.

I think for the wrinkles, my guess is he'd recommend soaking the shoes and stretching over a good shoe horn. I don't think the iron is necessary.

He even will leave shoes out in full sun to bleach out dark colors.
