Cream Colored Ugg Sweater boots

These are in great shape and by looking at the bottom soles, they have not been wore much. I bought them on an online platform as used like new. I don't think I ever wore them because they are the exact same color as another pair I have with side buttons. I thought these were lighter in color than they are and there is no reason to keep two of same color. I do want to point out that the back heel where the ugg tag is seems to be a little discolored and almost gray in color if they were and suppose to be cream when new? They was like this when I got them.
