1000 Mile Heavyweight Walking Socks incorporate a 100% Tactel inner layer that wicks any perspiration away from the foot to the more absorbent outer layer.
The ribbed outer layer hugs the foot but gives a high volume to fill traditional boots. It also makes the sock more durable and warmer to wear. The double layer construction eliminates friction between the boot and foot , helping to prevent blisters and increase the lifespan of the sock.
