    Whether I am putting on my Navy uniform or grabbing my backpack to knock out some heavy miles on the AT, these socks are essential. They are soft and comfortable but also tough out a full day in the rain or on a small boat. They stand up to days of abuse in my boots and trail runners. And after a wash they are like brand new. I have tried many other brands and standard issues, these are the best!

    Serious foot protection


    I wore the KX (hiking) sock every day for 24 years, but switched to the TKX (trekking) while healing from plantar fasciitis & Achilles tendonitis due to a barefoot injury 2 years ago. I now wear the TKX year-round. They are not too hot in the summer, provide sufficient warmth in Maryland winters, and have excellent padding and protection in the important areas. The KX also provided needed support and cushioning while shoeless at home, but the TKX feels like walking on a cloud. And they last 3-4 time longer than average socks. For 26 years I have been recommending them with confidence too everyone I know who complains about their feet.

    My feet feel protected, but there are some shoes that I can't wear with these as they are sooooo thick.

    Extra comfortable and cushy socks, really thick! Make sure your shoes are not too tight or you won't have room for these fantastic Thorlos.

    Best sock for standing on cold/winter concrete floors all day!!!


    I am on my feet all day long and keeping my feet warm & dry is almost as important as sharp tools when working in the shop during the winter months. I even wear them during the summer, when working, with my sandals for the extra cushioning.

    The One Sock To Rule Them All


    These are my socks, and have been for decades. Running, hiking, backpacking, riding, every-day go-to-work, and I sleep in them too. I need no other sock!

    For me, there are no other socks to talk about.


    The TKX are the only socks in my sock drawer... and have been for the past 15 years. What more do you need to know. Buy the best, cry once! The care directions are very helpful. The inside out washing and drying part along with fabric softener keeps these alive forever. PS keep your toenails clipped so that the socks don't prematurely wear out as the fabric doesn't like a sharp or rough edge. PS Please bring back the blue color, as they work better with jeans and much of what i have to wear. Thank you.
