What differentiates Thorlos from all other socks on the market today is our clinically-tested padding. It is our core technology. It’s the key to the protection and comfort you are guaranteed when wearing Thorlos clinically-tested padded socks. You can see the difference yourself, simply by turning Thorlos padded socks inside out. Once you have the padded sock inside out, you will notice how dense the padding is—and if you squeeze the padding, you will feel how resilient it is. How many loops? Ten of thousands! We use our exclusive THORLON yarn and other proprietary yarn blends and fabrics to wick moisture away, ensuring a protective environment for your feet.
