    These are excellent. I bought a pair as a gift for my daughter who experiences a lack of circulation in her feet. They are always cold in the winter. But not anymore. She reports that she wears them everyday that her feet get cold and they are warm within minutes. This could be a new market for you.

    Excellent product. Comfortable and well-made. My podiatrist stated his helplessness for my Primary Raynaud’s because he said he had the same problem (he was about my age) and asked me to wear socks having a better insulation! HotSox has allowed me to avoid the symptoms for this third winter of 2018-2019.

    Another amazing Fortress product. Works as advertised, very comfortable, warm yet breathable. Super just for wearing around the house and snowy yard!

    My girlfriend loves them.
    The problem of many women is solved.
    HotSox from Fortress. I bought them for my girlfriend because she always has cold feet. What man does not know this problem. Since we have the socks, she wears the HotSox constantly in the house.
    The winter can come.
    Greetings from Germany
