I find that I wear the same size in Converse Chuck Taylors as Alden Barrie, Trubalance, and Van lasts.
With running shoes, I find I am true to size (whatever that means anymore) and in "normal shoes" (not sure what that means) I size down a half size.
I write this in the hope that it helps you size your Alden shoe purchase.
Which ones are you looking to procure?
PS: You may want to experiment on eBay before you pay full retail on a pair of Alden...
