KEEP YOUR LEGS AND FEET WARM AND COMFORTABLE Lambs wool is one of the best natural fabrics for warm knee socks. Because of the crimped nature of its fibres, the air gets trapped and forms an effective coat of heat. The finer the fibre, the more crimp it adds and the better insulation it provides. With just the right thickness, these merino wool long socks will be comfortably worn with your regular winter shoes or boots in winter weather when it starts to get chilly.
