I have just worn these boots twice, but I love them! They are comfortable and warm. I ordered down a half size and that is best for me. I read lots of the reviews before deciding to try them and felt they were so positive I needed to try them myself.
I found the recommendation to order next size up for half sizes to be in error. Next size up TOO big - especially when card enclosed with boots explains that boots should fit snugly until lining adjusts to foot. Otherwise I like the boots a lot - warm and snug.
