We had mail from a customer from Buckfastleigh this week. He has been wearing a pair on Indestructibles for 42 years! He said "I have worn them whenever sturdy socks were required, wellingtons, gardening footwear etc. I wore them yesterday with safety boots whilst re-roofing the garage. I am retired, but the socks aren't!"

 

The previous record was 39 years - I wonder whether anyone can top this!
