Proper leather shoes

I
They're a (US) 9.5D, whereas my shell derbies (also pictured above) are 10D. Both Barrie last. I would say I'm a large 9.5 in UK sizing so 10D is probably the 'correct' size for me in the Barrie,

Might want try a 10 1/2 C. What did the Brannock device--- every shoe shop in the US has them--- say?

but they didn't have these in stock. They did however have a 9.5E which I was surprised to find did actually feel like it fit fine and was actually a tad wide.

Go long and narrow and NEVER short and wide..
