Very comfortable.  Can be worn for a full day around town.  I have 9w feet, and somewhat large calves.  The sizing was spot on--just right in the foot and snug but able to zip on the calves.  Sadly, I waited to get calf-high brown boots just as the world is switching to wider ones (to tuck pants into).  Still, these will be great w/ skirts in the fall/winter for years to come.  Definitely a good investment.
