I've worn K-Swiss Classics for several years.  They're comfortable, don't go out of style, and always available.

These shoes are severely uncomfortable in comparison.  The heel cup cuts into my heel, and the tongue is not plush but feels like cardboard.  Truly horrible.

I left these in a hotel during some travel, and was about 5 minutes away when I realized it.  I decided it wasn't even worth it to go back for them; good riddance!
