This winter I have really been suffering with cold feet - to the extent it has been putting me off riding. On the recommendation of a friend I have been looking at these for a while, but was put off by the price tag (£160!). Finally they came down in price in the sale at wiggle (was £84.99 now £99.99) - and they are awesome! Last week I rode in subzero temperatures, and everything else was freezing apart from my toes! I went for the 45 (same size as my shimano shoes) and there is plenty of room for a couple of pairs of decent thick socks. I probably could have managed with a 44, so it might be worth trying both if you are small in one size. They are pretty bulky, but that's to be expected. They seem comfy on the two rides I've been on wearing them, and they seem like they will last (certainly better than my overshoes!). I would highly recommend them!
