This boot is a WOW!! excellently crafted, very warm, comfortable and style. I did size-up as it does run small in length size. However, it is worth the time to exchange the boot as I did; or, just read the reviews as I failed to do. I did order a second boot and I love this boot and will continue to purchase the boot for value and style. Customer service was excellent as well; when I did exchange the boot for a size-up. Again, thanks Amazon.com for wonderful shopping experiences.
