Peds Womens Countoured High Cut No Show Socks, 12-Pairs

i heard really good reviews and feel bad for returning them (carbon footprint and all) so i kept them. On top of not having gel tabs ("Gel tab keeps liner in place.special size type: standard.weave type: Knit") at the heel, the elastic does not hold up, and the socks seem quite thin so probably not for sports. I'm UK size 5, US size 7 if that helps.
