I have two packs gained from this brand socks to have rest for some time. I wear mostly at home in Nike shoes or she loves doing this. Already after two weeks of a pair of caught on the bottom dissolve. After three weeks, there were 5 pairs etc .... CONCLUSION: 24 pairs of socks which have 4 pairs were acceptable within 4 months break. Say in the average score holds a pair of whopping over 6 days !!!! Normally washed 30-40 degrees Ariel, not big claims how to halt so wearing socks. In a response from the seller, I wait until today. Had previously sometimes PUMA socks who held very long, so I think that it either is not true or PUMA has really diminished in quality.
