10 miles in on these fantastic boots 10.5 D is a little to big for my fit - for reference I fit 10.5D in Red Wing Iron Rangers , 10D in Whites boots ,10.5D in Grant Stone. These would fit more like a 11 D in iron rangers. I tried to adjust with insoles, but I need to reduce my boot collection. I I wore them about 5 times and always used a shoe tree and cleaned after worn, The brown patina is just starting to show- I know it’s a big purchase but just look at the videos on this boot
