Been playing pickleball for about 4-5 months now. On Mon & Friday, I play for about 2 hours then join another group about an hour later and play for another 2 hours. I've been doing this for about a month now. Needless to say, by the time I'm done, my feet are really tired. Tried out these socks last week and my feet were noticeably better feeling. They were still tired at the end of my play sessions, but not as achy as before & not quite as tired. Hope this is a new trend. If so, I'll def be buying a couple more pairs!
