To repeat others' comments... to each his own. People think the stuff I put on for a simple bike ride is excessive and an ordeal (bibs, baselayers, jersey, windvest, socks, shoes, oversocks, arm warmers, gloves, cap helmet, Road ID, reflective wristbands, etc...), but I don't feel that way.

As long as their shoes/clothes are not compromising theirs or others' safety, I think it's great that they can show others that bike commuting is possible without looking dowdy. I've worn a pair of Robert Clergerie loafers on my commute, along with my Burberry backpack and peacoat. If I can influence a single fashionista to get out of her car and onto a bike, all the better I'd say!
