The Rockport DresSport slip-on are a bit too casual for some.  It is a good comfortable shoe ok for travel which is what I bought them for.  But I prefer a shoe (loafer/slip-on) that I can also wear with a suit as I travel often and prefer not to carry extra shoes.  These are just awfully casual looking, never work with a suit or even a sport jacket and dress pants.  May be ok with a pair of Dockers and they look ok with jeans.  I have two pairs of the DresSport oxfords and I can usually get by wearing them with a suit if it is not a formal event.  But this slip-on just will not work.  Rockport got close on this but they sacrificed a bit of suitable style (pun intended) and came up with more of an earth shoe style.  They should have stuck with the sole/heal design on the first generation DresSport oxfords.  I may send them back as I can find a much less expensive shoe to wear with jeans.
