As an owner of at least 25 pair of smart wool, I know what you mean.How the heck do you decide on which sock buying on line? I just checked out the smartwool and darntough websites and it's a sea of socks!
Mine just keep on going for YEARS (some I’ve had for at least a decade.) No special care. Throw them in the washer, dry them in the dryer or window sill…Another fan of Smartwool socks .
