Replied to this sizing question on another thread on here, but our boots fit very true to size, in both width and length, and we mean that in the most literal sense. All of the lasts we build our boots on are sized against a brannock device, which is the metal foot sizing device in shoe stores, footwear departments, etc.. From a quality control standpoint, many companies out there don't strictly adhere to the brannock for sizing, which muddies the water a bit on size comparison between different brands, styles, etc... In my experience, our boots fit very true to size. Having said that, I pretty much always size up a half size in everything I wear, as I like more room for my toes and a heavier sock when needed. For example, my foot measures a 10.5wide and I wear an 11wide in our boots. I can fit the 10.5 just fine, but like I said, I personally like a little extra room.
Hope that helps
