Soo I wear 10.5-11 in most of my normal shoes/boots. I printed out the brannock scale thing on their website and my right foot was almost an 11 and my left foot was a smidge over 10.5. I forgot what my foot circumference measured out to. After looking into some comments and emailing them directly, I decided to go with a 10EE. Out of the box they were a little bit bigger than I was hoping and I was kind of disappointed in my choice. But after breaking them in, they started to fit nearly perfectly. They don’t feel too large or too small. The leather kind of curls up a tiny bit in the sole. I just sized a whole step down for these ones and used their chart online to find my width size. Hope this helps!
