Madewell The Brady Lowcut Bootie in Bone, Size 7

Madewell The Brady Lowcut Bootie in Bone, Size 7 Pre owned, but in really good condition as I just have never really had them in heavy rotation. I find these run a bit big as I'm usually a 7.5/8. Leather is in nice condition (not too many lines in it), but there is one mysterious blue spot on the heel of the back left shoe (pictured!). Let me know if you have any other questions :)
