How often should the socks be washed and what recommendations do you have for temperature, detergent and drying?

We recommend hand washing in warm water and air drying. You can use mild soap. If washing in a machine, please use a gentle cycle. Always do your best to let it hang dry. It's imperative that the garment be washed after each use! Washing brings back the elasticity of the garment; this ensures you're getting the proper compression and prevents them from rolling.
