I'm pretty thorough when first researching a product that I want to purchase online, so it was good that I heeded the advice of dozens before me that bought this boot. Their collective advice was to purchase a size smaller because these boot sizes run rather large. I wear a size 12 in all types of footwear- dress shoes, tennis shoes, hiking boots, sandals et al, so was hesitant to purchase a whole size smaller. I did go 1/2 size smaller and am very glad I did, as the sizing of the boot is generous. I could have probably gone a whole size smaller, but it is just about prefect wearing two pairs of socks. Being in the Northwest, two pairs of socks is de rigueur most of  the year anyway. Think of these boots as kind of like finding your most comfortable fit in pants. If your best fit on your waist is a 33, you can wear a size 32, and they will eventually stretch to fit after wearing for a while, or with a size 34 you can wear a belt. There is some small slippage on the heel when walking, but according to boot makers there is supposed to be. This boot looks better than the picture. The leather looks 100 years old, is rather thick but very pliable and feels great. The sole is heavy duty. I don't expect to wear those out for many years. All of the seams on the shaft of the boot are on the outside so there is no internal chafing on the skin from seams if your ankle/ lower calf is not covered by socks.  They look great with jeans but I also wear them with casual Dockers. I've had them for a month and they feel like I've been wearing them for years already. Great boots!
