I went to several websites to search for reviews on this boot. Majority of the people said that the boot runs small and to go a size up. I'm so glad that I did, otherwise I wouldn't have been able to get my foot all the way through the boot. I wear a size 8 and I purchased a size 9 and the boot feels like an 8 or 8.5. It's perfect. The shaft is narrow, but that's a personal choice. I plan on wearing these with either leggings, skinny jeans or with skirts. The boot is absolutely gorgeous! Words cannot express the detail on this boot. I can't wait to wear them and see everyone's expression. I purchased these in the color brown, for the Fall season. So many rainboots come in Spring colors. I was looking for a detailed brown boot and I finally found it. I did measure my calf (leg) to verify that the boot will fit. The boot does leave me a good inch of room. The bed of the boot is very comfortable. Almost like wearing sneakers. I can't believe that I got these on sale. What a great find!!
