I got a pair of these for my birthday and was mighty excited, however when i went to put them on, i struggled to get them up my legs. For one size fits most, its more like one size fits tiny (legs. The foot part was fine). I don't have big legs by any means and i'm a sz 9 in shoe, but the socks are made tight, and where it says Gryffindor, the stretch is less than the rest of the sock and i found it pulled at my leg muscle. I was disappointed to say the least, I'll possibly wear them around the house, but i'm not sure i can wear them for too long in fear of getting cramps. I wish i could return them for a bigger pair, but that doesn't look like a thing.
