When you're riding in windy conditions, your feet need a little protection too. That's why Castelli dreamed up the Duo Windstopper Sock. Windstopper X-Lite fabric prevent wind chill from freezing your dogs, ultralight construction fits nicely with your shoes, and flat seams prevent discomfort on your all-day rides.
I ordered these after concluding that overshoes were not really doing the trick.These are expensive for the what they are - socks. The bottom of the sock is so thin, I have to be careful not to rip them putting them on.They do seem to be blocking the wind which is what they are designed to do. Wearing them on top of some rather thick Assos socks, in SIDI shoes with PI cyclone toe covers, they have been keeping my feet warm from temps down to 35F so far.My one major complaint is that the tube part of the sock as it transitions to my leg, is really loose I wish it were a lot tighter to make a windproof seal.These are basically a made in italy gore product with both Gore logos & a Castelli logo stamped on it.
