-28C but I decided to ride anyway since I already missed 1 of my 3 commutes for this week on Monday. Swapped out the clipless for platforms and wore my heavier boots and electric socks. I didn't turn the electric socks on and my feet got cold toward the end of the ride. I didn't want to bother stopping and fiddling with the batteries and snaps, which can be tricky enough to do while inside. Regular pedals don't work very well with my boots and I could never find a comfortable position. I have clips for the pedals but the boots are too big to fit in them.

The rest of me was toasty warm. 4 upper body and 3 lower body layers. I still haven't needed to add an upper body wind shell, but keep it in a pannier just in case. In addition to my stretch balaclava I also wore my beanie which may have been a bit much.

I think this may be the last of the extreme cold, starting tomorrow the forecast is for temperatures just below 0C.
