My husband gave me a pair of these last Christmas and I love them!  I've been trying ever since to get him a pair, but the XXX size he needed was unavailable until just a few weeks ago.  He is delighted with them also. They are incredibly warm and comfortable--like going barefoot but toasty!  I washed mine once and they did ok, but I suggest the gentle cycle, then roll and squeeze them in a towel rather than using the spin cycle to remove extra water. Tumble dry on low. They run a little small (the XXX is more like a 11-12 men's than a 13-14 as stated), so you may need to order one size up from your usual.  Great purchase, couldn't be happier!
