Sizing Chart Link:

Please note! Sizes are in inches, not regular shoe sizes. We get a far better fit by sizing this way. Measure your foot from ‘back of the heel’ to the end of your longest toe. We suggest that you go UP 1/2 inch from the size you measure on the tape, for comfort.

    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.
