The 6.6 seemed to be more form fitted, but there was extra length in the toe for what seemed like the proper size. I was trying on 40.5 and 41. The ball of my foot hit at the right spot in the 41s.
To elaborate: My toes felt cramped in length in any shoe below 6.6 (5.5, 5, and under), but there was more volume in the mid and forefoot. I needed 41s, but they seemed a tad wide. 40.5 in the 6.6 seemed like the right length, but a little narrow, and the wide part of my foot hit in front of the wide part of the shoe. Good in the heel cup. 41 seemed like the correct length for the last shape even though there was empty space in the toe, and the midfoot was more comfortable. I would have to adjust the heel cup retention thingie smaller.
Hopefully those comparisons can help you make your decision.
I usually wear Specialized shoes in 40s, but I have some heel slip, so I wanted to try the Sidis. I'm not sure they're worth the extra $$, because I'd want 6.6 or ergo2. That's good to know about the men's last. I couldn't find any men's to try on in my size in those shoes to compare.
