These are very comfortable but not quite as warm as I was hoping. I forget that most winter shoes are designed for European temperatures. Iï¿½ve been using shoe covers for anything below 40 degrees, from 40-45 my feet start getting a little bit cold after 60 minutes or so but never painfully cold. My feet do tend to run cold and I donï¿½t like wearing extra thick socks so these are probably warm enough for plenty of cyclists, the fleece lining does seem to be pretty effective as well. I like that these to not come up very high on the ankles as well, my dexterity or lack there of has not been effected. I donï¿½t really like how the cleat position is set back on these though, I have them all the way forward and Iï¿½m still getting the occasional toe rub on turns when Iï¿½m not paying attention. Itï¿½s not uncomfortable Iï¿½m just used to a more forward position.
I am so happy with this winter shoes. I had the Fizik R5 Artica ( not the GTX ) but it was heavy and rubbing against the crank arm. The GTX is suave! I used it 3x on 35-42ï¿½ and added a toe warmer, my toes were warm on my entire 40, 50 miler rides.
I rode over 2 hours and had no frozen feet when I finished my ride. high temperature was 45 degrees , little sun, the first real winter ride here in Colorado. The shoes are very comfortable and it was way less hassle then shoe covers. I wish i had had these in the mid 1980`s when all they had were the Sean Kelley`s Belgian booties. Quality product, worth the price if you are a year round rider like myself. Cheers, viva velo
