"rikod, since you've got Alden, AE, and Vass, how does your Barrie or AE 5 last compare to Vass lasts' shape and sizing?"
Very different, AE seems narrower with low instep, Alden wider also low instep, Vass lasts higher instep. I wear US 8D in AE and Alden (Barrie 7.5D) and about 40.5 in Vass, all fit well.
