Update.
I'm am very, very impressed with my boots (the Celsius Artic version).
I've ridden with them several times when the temperature has been below or around freezing and my feet have been OK. They would have been better if I'd worn thicker socks.
Today I did the Mere 200 Audax. Since I knew that I'd be out for over 12 hours, I wore silk liner socks, knee length ski socks and Endure Deluge overshoes on top of the Northwaves.
My feet stayed toasty and dry except for the left which got wet when I cycled through one of the many floods and the water turned out to be hub deep. Some of it went over the top and into the boot. Even so, my foot stayed warm enough.
Rider wearing conventional shoes and overshoes weren't so lucky. Many of them were complaining of cold feet.
My GF was so impressed by my boots that she bought a pair yesterday.
CRC are the cheapest that I've been able to find but it's worth noting that
Evans price match (at least they did yesterday) and you can try them on.
I've a feeling that they'll turn out to be some of the best cycling kit that I'll ever buy.
