I purchased the sand color UGG Bailey Button Triple Winter Boots in size 8 for my daughter who wears a size 9.  The fit is perfect and comfortable for her.  Although the color is light and prone to dirt and stains, there is no appearance of scuffing or dirt oh the side or top of the boot.  The material is reasonably resistant to soiling.  With that said, I still plan to purchase and use the UGG leather protectant.
