I am on my 3rd pair of this shoe.  Love it.  I take it everywhere on trips. Only shoe I used on a trip to Europe since I didn't want to wear sneakers.
Comfortable, stylish, goes with everything.  I wear a size 7.5M and bought an 8M since often I use sock or inserts.  I have another pair that is 7.5M and it feels small, definitely, 1/2 is right.
