So far, the best fit has been Gaynor Minden 11 M 4-121-22, but the shoe feels a little bit too narrow, and GM only goes to 10.5 for their wide size.
Went to try more shoes today, and came home with Bloch Serenade 6C and Suffolk Solo 6 XXXN. We’ll see if either of these work out. Also, why can’t they standardize shoe sizes?
