I wear 39.5 women's Sidis and for winter have men's 40 Sidi Hydros, which are described as being roomy enough for thicker socks, so I'm not sure that's the comparison you're seeking. They're definitely loose and feel roomier in the toe box beyond the extra half-size up. With very thick wool socks they're comfortable and warm enough in the low 30s, but I usually don't ride more than an hour and a half when it's that cold. I think there's enough room that I could add thin liner socks or toe warmers for colder temps.
