We’ve learned one of the best practices to lessen our sock impact on the earth is to not do something – wash them. Or, not wash them as often. We’ve tested this and understand the science behind it. Some of you wash your socks before returning them on warranty. Some of you don’t. In the past we’ve asked they be washed – out of courtesy to Sara (Darn Tough Warranty Warrior) – but we might pull back from that request.
