Now I know how they compare.. I have pretty wide feet and my old broken in Dominator 3's in size 43 (normal width) had a glove like fit and were very comfortable after years of service. The only thing was the toe room. My big toe was pretty much at the end of the shoe with hardly any room to slide forward. I'm sure I would have been fine with 43.5.
Fast forward to today. I received the Northwave Strikers that I ordered. I read online before I ordered that the shoe was naturally wider than the Sidi's and also it has a bit more toe room. I went ahead and ordered 43 again and the fit is awesome! It feels slightly wider than the Sidi's and toe room has increased by a few millimeters. Perfect fit. The plastic buckle is nice as well. It has a ratchet system but also a button to release it out one click at a time to fine tune. Pretty nifty.
I'll update once I get time in.
