"These are sexy looking boots. They are quality made and sturdy. The material is on the stiff side so you don't get boots that slide down. The calf circumference is pretty narrow and would fit skinny legs well. I have trouble finding boots that aren't ridiculously wide on my 13" calves. These still look great even though they are slightly bigger around my calves. These boots do run small though. I normally wear a size 8 in boots and I had to get an 8.5 in order for them to fit my feet. I am very pleased with these boots and wish I could find more that fit my calves so well. I haven't had them long so I can't comment on the problem with the zipper that another reviewer mentioned. I just try to be careful with them knowing this could be an issue."
