Bought these for our recent week-long tour of the Highlands as, having seen the weather forecast, I didn't fancy wet feet the whole way around. they're not cheap (25 quid or so) and I was a bit skeptical about how effective they'd be -- would they be waterproof? Would my feet just end up getting all sweaty anyway? they were actually really good -- we had a couple of days of solid rain and my feet remained pretty much dry and warm, while my g/f's feet (with some "water resistant" overshoes on) got soaked and cold. I had heard reports of water leaking down the top of the sock, but that didn't seem to be a problem for me. They're multi-layered and do feel a bit odd to put on, but once on feel comfy -- I was pretty pleased with them and I'm sure they'll be pretty good in winter, too.
