I have actually tried 2 pairs of these.  I normally wear a 10 with most brands - in this a 10 was too small length-wise but the width felt OK.  I tried a 10.5 and it was way too narrow to the point of causing pain within an hour.  I thought they would loosen up but no dice so far. Also the quality as a whole is pretty spotty, the stitches are uneven and the air pockets are not consistently located.  Nice looking shoe but the sizing and quality are all over the place.
