    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

    These are ok for walking


    I like these socks overall. They do not provide enough cushion for me personally. They are a very well made sock consistent with all Thorlo products. I wear them around the house and with my work shoes. I prefer the mini crew running sock for my daily 8 to 10 mile exercise walks. I love Thorlo products

    Smallest size is too big


    My thorlos hiking socks fit and feel great. These unisex socks are way to big. I wear a 6.5 shoe and these say for 6.5. Love the feel though.
