This one is unlined, right? I have the LS version and I completely agree that it is sleeker than the stock PTB. I think the single flex sole goes a long way to changing the profile. I've found them to be extremely comfortable. The unlined shell has creased less dramatically on mine as well, though that may have to do with the sizing.
Is the photo your pair from Alden SF?
Correction: they are indeed unlined. The heel counter is lined, but the forefoot of the shoe is totally unlined (i.e., green on the inside of the shoe).
What I was told by Alden SF re: creasing is that this shoe creases differently, rather than more than, the traditional version. Since the shoe flexes more with your foot, it develops a greater # of smaller creases, as opposed to the traditional (lined) version, which "breaks" more, resulting in fewer large creases.
