So far I’ve had them for only a week, I have yet to wash them so not sure how they will hold up after that yet. I have seen a bit of the thread looking like it’s coming undone but not completely sure and again I need to see how it holds up after being washed. I also try not to wear one pair back to back just because I don’t want one to get worn out too fast. It takes a bit to put them on as opposed to regular socks. Overall I really like this idea of the separated toe socks, when you put it on correctly it feels very comfortable and it feels like my toes get more support while walking. This is a good started pack to buy if you want to see if these type of socks are for you, I definitely will look for better quality ones though; not to say these are bad but I just feel like there is better.
