I respectfully disagree. Perhaps it is because we are in different population segments? I am in my 20's (barely) and until recently worked in gentrified Brooklyn. Alden is very "cool" among those I encountered there.
They are generally "cool" among those who wear a lot of clothes from J. Crew.
That could be it. I'm in my lower 30's in Washington D.C. and I can honestly say that I hardly ever spot Alden sightings on the street (and I look...probably more than I should). However, the folks I work with consider shoes over $100 to be trendy no matter the style.
