Read Rola's thread about his Hydroskin socks and that might be an option, but wanted to ask about shoe covers. I'm with Rola that getting cold just plain sux. I got a pair of PI gloves that have made it possible for me to ride in colder weather ( 25 F or so ) but my feet get numb. So far it has not impeded me as my rides are relatively short, but next year I am hoping will be a different story. Any suggestions/recommendations?
