Got a pair of these. If you have a narrower feet with a lower arch, it will fit you. If you have wider feet, annd especially if you have a high foot arch, forget them. With my high arch feet I can barelly put these on with the BOAs fully opened. Will send them back.
The width in the forefoot fits most similar to the Giro empire/imperial. I haven't done a lot of miles in them yet with the winter weather here, but my initial impressions are that they fit comfortably and don't give me any hotspots while pedaling even on harder efforts.
