I switched from Sidis to Specialized recently - love, love, love the new shoes. They have a much more square toe box. No more pinched toes. I also like that I can actually get a high end shoe, unlike Sidi that doesn't make several models in my rather small size. I understand that they will even be bringing out the uber high end S-works shoe in women's sizing this year - its on their web site, but not available yet.
