I ride a lot in cold wet weather. I have an older pair of Sidi winter boots. I LOVE them... even though they are too big. I take a 37 in Sidis and the smallest I could find in the boots was a 39.

I wear them with a thick pair of socks and an extra pair of insoles. I still wear booties over the top to keep the water from coming down through my socks. They make my feet very, very happy.
