They are quite comfortable believe it or not. and the length is just right. If you've seen Miranda Kerr and her Hermes boots this one is about the same effect length wise. I'd say maybe 2 inches pass your knees and it really compliment your figure. I'd wear them with a short sweater dress so that a moderate amount of my thighs could show up and it makes my legs look longer. I'm about 5'6 and 108lb. For me personally, the shaft opening could be a little smaller but I'm slim. I love the back of the boots being elastic and I'm thinking about sewing it to be tighter around my calf
