I kind of do. While i can't tell the difference between Aldens and whatever else a guy is wearing (most of the time, anyway), I can
tell if he cares about his style/how he looks by how well his shoes go together with his outfit. I guess I do kind of pigeon hole guys when I meet them based on shoes, though. What's funny is that I don't think the shoes themselves are ugly, but I correlate how I imagine a guy's personality and tastes would be based on his shoes.
ie: hiking shoes = guy either getting his BSC or in grad school for something to do with biology/zoology, probably grew up in a smallish Canadian town, probably likes Vonnegut books and reading philisophical theory and thinks it makes him artsy, has simple tastes but loves Indian food, hates shopping and girls who wear make up, doesn't understand 'pop culture obsession' etc etc...
I'm probably wrong most of the time, but I can't help the pigeon-holing.
