Dd(8) plays football a couple of times a week. But once she has worn football socks more than a couple of times, they get really stiff and very hard to put on (to the extent she needs my help, and it’s hard for me to stretch them enough to get them on).
I can’t buy a size up as she’s at the bottom of her current size range. I’ve tried soaking them in fabric conditioner, but it didn’t seem to make much difference. Is there anything else I can do to keep them soft and flexible?
