My first pair lost both pom pom bobbles within half an hour of wearing. Returned to store who were more than happy to refund and I ordered a new pair. Within 2 days exactly the same happened again. This time I kept them and trimmed the white string dangling off the side.They also shed a lot of fluff. 4 months in wearing daily and my black socks come out pink. Unfortunately very poorly made. They are comfortable but I wouldn't buy again.
