They fit well, same size as my F and P2, a little more snug in the ball area of the foot but no problem there. I can see how the U is difficult, if my foot was a bit wider and my instep higher I would take 1/2 size up if that makes sense. In short, for me, the size was a success, I can understand how others would need to size up, with the right instep, kind of tricky. Wide feet and low instep need not apply.
based on the pictures you've posted your G&G looks more girlish, imo.
Interesting, could you elaborate on the reasons?. I haven't compared them side by side. I will post a shot of both whole cut side by side to compare. It's kind of a half joke (half serious) anyway, I really like both.
