I am very pleased with my purchase of the Anne Klein Cailin wide shaft boot. They are well made, stylish, and very comfortable. I wore them to work the day after I received them. I had them on from 7a.m. to 7p.m. I was afraid that I may not be able to keep them on all day, so I brought another pair of shoes with me to work so that I could change into if my feet hurt. There was absolutely no need to change shoes. These boots became more comfortable as the day wore on. I wear a size 8.5 with calf size 15.5. I've looked around for boots that would fit my calf, and also be able to tuck pants in. I wore slim fitting pants that I tucked into the boots and I still had space for my pinky finger.  I love them.  If you are looking for something that is classic and stylish, then these boots will fit the bill.
