I can't believe the good reviews these socks get. I've tried a few pairs and they've all leaked, filled with water quickly under moderate conditions, been freezing cold, and a waste of money. In fact, they've been worse than anything I've tried before or since, I'd be better off putting my feet in plastic bags full of ice and throwing my money out the window. I initially thought I'd just been unlucky with the ones I'd got, but subsequent experience suggest the problems are endemic. Look carefully at many of the reviews and you'll see that they're just repetition or rewrites of marketing blurb. To be fair, you'll also find many positive reviews from apparently real users (as here), so some of the socks must work. However, look longer and you'll also find people who've had the same experiences as I've had. Perhaps it's "just" a quality control issue, but how can you know since Sealskinz never responds to anything you ask them? Perhaps the most annoying thing is that once they're full of water, usually within minutes, or even *a* minute, the water doesn't warm up or drain away. It just sits there blobbing around your toes, cold, cold, cold. Believe me, it's not a case of water coming over the top of the socks, I've tried standing in the bath with them and, yep, they fill up with water from around the ankles: squelch, squelch, squelch. Don't do it to yourself, you'll be irritated and feel a fool, save your money and invest in ordinary wool socks, good boots or shoes, and perhaps gaiters or overshoes. Accept that in most conditions your feet are going to get a bit wet and your job is to keep them warm. Or wear some sort of rubber boot, like snow boots. If I could, I'd give minus five stars for performance and minus ten for Sealskinz's customer service. Sealskinz socks suck.
