Found this interesting...I just bought the most recent 02’s in size 34 from S&S and they happen to arrive the same time as a pair of raw ROY KS1002 in size 33 I recently picked up off of eBay. When I measured both, measurements are exactly the same...exact.
I have footwear from Tricker’s, Alfred Sargent, Redwing, Astor Flex, Paraboot and various others. Room for a variety of styles I’d say. I’d go for the Bergerac - unless you want to wear them for hiking.
