Sidi is releasing the top of the range Wire Collection this fall. The shoes incorporate their own Techno 3 ratcheting system which should provide for an even fit around the entire foot. There are three different versions in the range, one with a Speedplay SP Carbon sole, another with the Wire Vent Carbon sole for standard three hole cleats, and the Wire Vent Carbon Women, a shoe specifically for women. I still have and use 16 year old Sidi Dominator mountain bike shoes, and they work as well today as they did when new. Sidi reliability and fit are a cornerstone of their products, and I suspect the Wire will continue in that tradition.
