I have only used these once for the Chilly Hilly ride in February on Bainbridge Island here in the PNW. They have a nice fit and kept my feet warm and dry until I walked on wet/muddy grass allowing moisture to get up through my cleat area of my shoes.
I use these covers in temps down to 35 degrees F. It's amazing how warm they are considering their light weight. Easy on and off and fit snug to the shoe and your lower leg. Very aero!
These are the bomb--warm, water-resistant, durable, and stretchy enough to be able to put on easily. Great for riding in the 40s and not as pricey as some of Castelli's other offerings. I've been riding my pair for 3 years now without significant wear. Highly recommended.
Very nice overshoes. They're snug, but still fairly easy to put on with the amount of stretch they have. Surprisingly warm considering how relatively thin they are. Can't (and honestly probably won't) attest to any waterproof/resistance capabilities as I really don't intend to ride outside in the cold AND wet. They also look great! Lastly, only time will tell as to their longevity and I've only had them a couple of months
Fit my size 43 fizik shoes perfectly and add a lot of warmth for Portland OR winter riding
