Q about BB (not Peal) shoe sizing

[Modernist]

I've used the search function and came up with nothing, except perhaps that Peal for Brooks Brothers run a bit wide. I'm interested in these:

I'm somewhere in between a US 10 and 10 1/2. I usually end up buying 10 1/2 and add anatomic insoles. Is anyone familiar with the fit of Brooks Brothers shoes?
