Got my Essex Tan Service boots today, can't wait to get some color on them.
A few notes on sizing. I have a wide foot...wear 7.5E in AE Dalton (perfect fit), 7.5D Alden Barrie (j.crew captoe boots: a little long, but good width). I ordered size 7 for the Service boots (2030) and they fit very good for width (close to the barrie boot), and good for length, but a little loose at the heel compared to the Alden captoe boots.
I tend to put in an insole in my boots, so they end up being more snug anyway, but the Service boot is still slightly loose at the heel with the insole compared to the barrie boot. I think 6.5 would have made it slightly tight for width, especially with an insole.
Very happy with them!
