    new for me


    These socks are well padded, but I notice on my longer runs(7mi+) that I really start to feel that extra padding on the ball of my feet. It can feel like a wad of material and be quite uncomfortable. I think I will probably will go back to your standard running sock.

    I was getting blisters on my heels and toes when running. I must have bought ten different brands of running socks all claiming to be the best and solve your running problems. I tried them all out and I have to say none could even compare to Thorlos. Of all the brands these were by far the most durable, comfortable, and best quality. These socks were the only ones that solved my problem of blisters and pain. The padding on the heel and toes is so thick and comfortable. I am throwing away all the others brands. I will only buy these socks for running from now on. A must have if you are a runner and want to treat your feet good.

    Best padding for heavy runners


    At #230 these socks provide the best heel & toe padding I have ever had. Most of the other brands focus on being light-weight and i suffer the consequences with blistered toes and heel wear-through.

    Very good socks


    These are pretty good socks. They have plenty of cushion and wear nicely. Not ideal for summer because they keep your feet very warm but for the other three seasons they are perfect. Highly recommend

    Best off road socks I have ever had


    I have used them in offered runs through rivers in winter and they are the best I have used. That is why I bought more so I have a good supply at hand for all my runs
