This is my Brannock size for each foot and my ball circumference is approximately 10". I ordered a 10.5D based on Nick's chart. These do feel a little long and I could possibly go down to a C width for use with thinner socks.
Right foot
10.5 length heel to toe
11 arch length
C Width (on the B/C line)
Left foot
11 length heel to toe
11 arch length
C Width (closer to B than D)

I ordered these from Nick's under their Cutter's Choice option. I didn't care as much about the color so I selected Seidel's 1964 Brown, 1964 Monarch and 1964 Mahogany as my three options.
