Wilbur, this is my second winter riding in these Keens through Fishers, Carmel, Noblesville and Westfield. I ride almost daily, and these boots hold up really well. I wear a regular (well, ankle length) Wright Sock, and since buying these last year I forgot what cold toes are. I normally wear them when it snows and when it's below 25-28F depending on wind speed. Anything higher than that but less than 35-38 and I wear an oversized trail shoe with a thicker wool sock. I specifically use size 11 trail shoe (I normally wear 9.5-10) to accommodate for the thicker sock.

P.S. I ride almost daily between 106 and 146th streets west of 37 in a loop unless the roads are really bad. I wish Fishers would have more bike lanes like Carmel.
