They're the warmest socks I own.

I spend most of the year with my cold feet perched on a hot water water bottle, so I thought I'd try these, to see if they lived up to the hype of being warm socks; and they do.

I sat with one of my usual thick winter socks on one foot, and put a heat holder on the other, and the heat holder was much warmer.

I gave them 4 stars rather than 5 however, as I found the fit to be far too wide around the foot. Yes, I'm used to tighter fitting socks, and my feet are narrow, but I could happily chop a couple of inches off the width of these, as the sock flops about around my foot. The elastic is a good fit around the leg though.

I'd be the first to order a drawer full, if a tighter (or more elasticated) fit becomes available in the future.
