My Audleys: What is the Problem?

Is it aniline or crust leather?

almost looks like excess polish problem, but that wouldn't make sense given that it is only on one shoe.

You are not the first one to bring this up about C&J crust leather handgrades. If you do a search you can see extensive posts of people thinking their shoes have a problem. It is not an issue, it is just crust leather. The leather comes fairly natural to the factory and the finish is built up using waxes and polishing at the factory. When you walk the natural leather shows through at the creases. It pretty much just patina's faster. I would use reno on them and rub in in fairly hard to get some excess finish off, then I would polish them with wax. If you want to deposit more color into them I would polish with a light coat of brown cream first, then wax. Over time doing this simple routine they will look beautiful.

I believe this is part of what makes these shoes "handgrade". Aniline dyed shoes come already dyed to the factory and then they are just shined up after the shoe is made.

if you dont like the look send them to get stripped and redyed a darker tone

Reno is Saphir renovateur. One of the best cleaners/conditioners for leather on the planet.

Getting them stripped and re-dyed I would send them to Ron Rider.

Lawman, FWIW, your shoes should be in the shoes with character thread.

most shoe and leather care shops should be able to do this. i use a prolific chain in my state (*shoe hospital)

ask to see some samples of their work

ive salvaged a favorite pair of shoes this way, after messing up the polish job.

I have the same issue with my dark brown weymouth, one side creases exactly like Op's. I thought it's normal, something to do with the leather character or property. The funny thing is that all this while I never thought the leath is dry, because it feels soft and bends soft, softer than the other one...

Cheap C&J's. There, I said it.

That's not cheap leather, that's the issue of very natural leathers. Some love it, some hate it. I like it.

Nobody has addressed the fact that this is happening only on the right shoe. I'm no expert, but maybe it's a quality control issue?

Leather is a natural substance and therefore different behaviour between tow shoes is not surprising and not in itself a defect. I don't think it looks too bad but using a dark tan polish or even oxblood would do what you want.
