Could whoever told you about the width difference have the Mega's? Sidi's come in 3 different widths.
No, the person who told me that half sized Sidis was a woman (don't believe Sidi makes Megas in their womens' sizes??), and she was told the 1/2 sizes were wider than the full sizes by her LBS. So much for their knowledge!
