That's the kind of fading I meant. The dye itself breaks down tremendously with exposure to the sun, faster than the leather darkens with exposure to sun. I certainly didn't expect the #8 CXL to act like shell at the creases, or have the same look as it pushes the dye/oils away from those creases. But I did expect #8 CXL to fade with exposure to sunlight, especially since as a summer shoe it would be exposed to a lot of sunlight. Instead, it's just a burgundy color that stays more or less a burgundy color.
Of course, now I have natural shell loafers, and #8 shell rangers, so I'll get that sun exposure this coming summer!
