Great socks - not much more to say.
Overall, I'm really impressed with Gore Bike Wear cycling products, and these booties do not disappoint. Over the past 10-15 years, I've never found cold weather cycling enjoyable because no matter what I tried my feet got cold on longer rides (anything over 90 minutes). Not any more! These booties are really warm, and you can even wear thin socks underneath. So far, I've been on rides into the upper 30's with toasty toes (with the thermo lined model). The booties go on relatively easily, but it can be a snug fit if you have shoes with a wide toe box (e.g. northwaves), but maybe that's a good thing to help keep the elements at bay.
It took many years, but I finally found a great cycling jacket. The windstopper works as advertised, and the jacket keeps me warm without overheating. Yesterday I wore it on a windy road ride with temps in the low 50's with just a short-sleeve base layer underneath. I was comfortable the entire ride. By varying the base layers, this jacket should easily be able to go into the 30's. Note: the sizing chart is wrong. I usually wear L jerseys, and ended up with a L jacket, although the sizing chart said an XL should have been perfect.
