Warm and cosy just like the ones I bought last year :-)

stanley p.

Good quality extremely warm socks

Bought for my Dad who wears them all year round- lovely warm socks. Last really well, apart from when he forgets and puts them in the tumble dryer, but even then still useable and practical. I'll be ordering more soon!


Keep feet warm in unheated house in winter, saves electricity bills. Good fit and very reasonably priced. Will be back for more, highly recommended

Holes form quickly by big toe.

Nice and comfortable but holes soon form despite keeping my toe nails clipped, Perhaps the ones with the yellow reinforced heel and toe would be a better bet and last longer than a couple of weeks
