I think it depends. I have a couple pairs of seconds and the Circle R is on the sole for one (Normal) and it is on the inside for the other because it has crepe soles.
This one is harder to see but it is there over the text near the heel.
As far as I know there is one place to get Alden Seconds, The Shoe Mart. Alden of Carmel has some listed from time to time but I am not sure what that means. I think that Adam just has high standards and
does his in house if something is not right when he looks at them.
I wonder however if TSM still receives all of Aldens seconds? I would think that make ups for specific manufactures may not be available tl them.
