they were mto
yeah, no such thing as Alden Walnut Shell Cordovan. AE has had some shell cordovan called Walnut however.
Anytime you hear 'Walnut' on Aldens, it's calf.
I have some Walnut Shell Boots and that is not Walnut Shell Cordovan. Mine are Rider Boot Co., plain toe. Awesome boot btw.
They actually have some on sale right now for $395. Great price for shell : http://www.riderbootshop.com/rider-boot-co-8420810-walnut-shell-cordovan/
They look pretty nice although I'm not too sure about the last and how it fits, etc.
