Rhetorical question (?): How long is a standard UK 11.5, for instance? Is the G&G 11.5 the same length as the EG 11.5? or the Lobb 11.5?
Where is the medial ball joint located on an extended toe 11.5 versus a more classically styled 11.5?
How about widths?
How long is a US 11.5? Where is the medial ball joint located on a Alden 11.5 versus an Allen Edmond 11.5?
I suspect that the correct answer is "no one knows." The answer is not out there.
Which makes all such comparisons meaningless.
