I typically wear Dansko clogs.  I'm very comfortable in clogs and find most other shoes uncomfortable.  Let's face it, though, most clogs are not so ideal on ice and leather isn't so great in slush and snow.  Enter this fantastic shoe.  Love, love, LOVE the traction on these shoes.  Plus they are waterproof and warm.  They definitely do run small.  I typically wear a 6.5 dress shoe/7 tennis shoe.  I ended up with an 8.  I wish there was a dark brown.  It would be easier to coordinate them with office casual clothes.  However, given their functionality, fashion can take a back seat to safety and warmth on a crummy weather day.
