I have two pair of these in black.  One is for work, the other for my workouts.  So supportive, comfortable, edgy.  Really a staple of my wardrobe.  Glad Keen offers half sizes.  These really are true to size, so if in doubt, go to the half size.  For some Keens I wear a 9 (sandals, etc., w/o socks), but glad I got the 9.5 in the Presidio.
