UGG Neumel Ankle Boots Chukka Black Suede Shoes Men's size 8

UGG Neumel Ankle Boots Chukka Black Suede Shoes Men's size 8 in EUC. Here's the weird thing though. I bought them as a pair. They are the same shoe and the same size. But one has a darker lining than the other. Weird. However, they look brand new and one even has the sticker on the sole still!
