I have owned these socks for many years, i.e greater than 5, or rather so many I can't remember when I bought them. I have numerous pairs and colors (although they are limited in their selection) and I wear one pair each week, so I would guess each one has been worn and washed over 250 times.I suffer hot feet and these were the only socks I have ever owned that don't make my feet sore during a days wear.The reason I bought more was simply the one's I have are starting to fade and although the elastic is still great, they are becoming more stiff and not as soft. (My mother who was visiting recently commented on how 'hard' my socks felt, so I thought it was time for some new ones).So, yes they are expensive, but given I'd buy new socks every year that were about half the price, these have paid for themselves many times over. Having said that, there's still sticker shock when buying them, but you have to get over it and try them.I just wish they did more colors, but at least they cover the basics.Go ahead, treat yourself, you won't regret it.
