When the walking and hiking miles start piling up, you'll be glad you've got 7-Year® Heavyweight Merino Boot Socks on your feet. Full cushioning throughout this entire sock provides support and comfort without unwanted weight and bulk. Soft, insulating merino wool makes 'em plenty warm, and we've added high-tech fibers to absorb shock, wick away sweat and even fend off blisters. The biggest deal?
