I recieved these as a warranty replacement from Northwave for my Aerlite SBS shoes that were coming apart . First impression was they are very ventilated. The mesh uppers breathe very well. The sole isn't carbon or carbon reenforced, so the sole is nowhere near as stiff. Having ridden a carbon soled shoe for the last six years, I am noticing the difference in sole stiffness, particularly on longer rides. The arches of my feet seem to fatigue over 50k, which is something I have never noticed. For winter riding I don't think the mesh upper will be very warm, but a decent set of shoe covers should fix that.
Quality so far is A+
Sizing is the same as my Aerlites so it is 1 size larger than my old Aerators.
