use this on cold wet days in New England. freezing to 22F, moderate wool socks and you are fine. Spray means nothing to these and the closed bottoms keeps water out from that direction as well. NO overbooties used yet - but if I enture out in teh single digits, i think I will go that way.
Very nice job Fizik! Great stiff lightweight road shoe. The speed lacing system works well, easy to get on and off. I have not tried in a full on rain storm, but I am confident they will keep the water out. These do run big, I usually get a 46, Sidi or Specialized. I got the 45 and they fit perfect!
