I must say, Jessica Simpson knows how to make boots.  I paid premium shipping to get them fast.  It is worth every penny.  I bought 4 pairs of her tall boots this season.  I love every single one of them.  These boots are gorgeous and very classy.  Excellent leather and shape.  My calf measures 13.5 cm and I have about 1 inch space at the opening.  I definitely have room to wear leggings or skinny jeans with  them.
