I love these Madden Girl Piinup Boots. They are super comfy - I've worn them all day (on my feet all day) and maybe after about 7 hours do my feet start hurting a bit. But I think after 7 hours on your feet in any shoes, your feet would hurt. These fall about 1" short of my knees. The heel is really sturdy. The grey color is gorgeous, and pretty true to the picture. I've gotten SO many compliments on these boots. Even my hubby loves them on me! LOVE these boots!
