My first 2 pairs of walkie's are 10 years old and still going strong: used for hiking, walking and just being. I have just ordered 3 more pairs and am thinking, perhaps to get another, just in case. I hope these socks are never discontinued. They have great cushioning, no bothersome seams, wick dry, don't smell (even after repeatedly wearing them (for reasons)) and are just the best socks for anything, period.
