The trend that size 11+ doesn't sell well? I don't think this is new.
11+ may not sell as well as the other sizes. But they do sell. And retailers have, as far as I can tell, typically stocked a few pairs up to at least 12 and often 13. A "trend" towards not stocking any shoes over 11 would indeed be unfortunate.
FYI, I have 3 pair of Aldens, all 12 D going up on B&S soon. One is Brooks Brothers color 8 LHS, two is a pair of black plain toe boots, calf, barrie, and last kudu indy's. Very lightly used, 3-4 times. PM if interested. Thanks.
Just in this week -- snuff suede short wings (flex sole, Hampton last) from Leather Soul. They are actually darker than the photo indicates. Snuff plain toe boots on the way from LS. It's a snuffy week.
