I only had it on for a few minutes so far but it seems to fit really well.  I was looking for something stylish but comfortable to wear to a fancy dinner at DisneyWorld.  I'm a plus size woman so comfortable shoes can be hard to find.  All straps fit well, the straps across the toes are flexible enough so that when my foot bends they don't dig in.  My foot didn't hang off the sides nor did my toes and/or heels.  If I remember, I will update this after my trip and tell how well they did with walking the theme park for a few hours.

UPDATE:  They worked for my trip.  I would not recommend walking miles in them, but for shorter jaunts they did great, were comfortable and looked cute.  Never had any problems with blisters and the arch support is great. Even got some compliments on them.
