I rode last year in the cold with wool socks and no-mesh shoes(using platform pedals on the comfort/hybrid)--even used double layered wool socks on cold days in the 20s days, especially the ride when it was 22ºF with a wind chill of 12º. Of course last Winter I only did 23 mile rides and now I ride 30, 35, 40 or more miles so I'm out a fair bit longer. I'm thinking on days when it's in the low 30s and in the 20s using toe warmers for the feet and maybe even the hands on the really low days. I have some gloves((two finger + thumb)mittens with another glove insert) for the days with the really cold temps.
