Another one with 22degF here for my morning commute. Nice and calm and amazingly still dry. Still on the road bike too. I am really stretching it this year. Tried my new neoprene booties over my cycling shoes with a thin merino wool sock. I was not cold at all and it only felt cool. I think these will be great to extend the clipless pedal usage well into the winter if not all of it. When it gets into the single numbers will be the real test. Last year I had to use thick wool socks and insulated hiking boots on platform pedals and I was never cold all the way down to slightly below 0. When it was well below that I got cold but pressed on.
