Blown away with the difference these winter shoes make. Dry and warm feet in all of the conditions I've ridden in so far this winter. That includes temps down to 28F, rain, and mud.
The only thing different about these is the closure is more like a hiking boot. I think the more expensive model is a BOA.
I wear US 11 1/2 shoes and have narrow feet. The size 46 in these is perfect for me with thicker winter socks.
