Alhamdulillah, this socks does what it says. worth the price. been wearing it for more than a month. doesn't sag, feels comfortable despite the grips on the sole (you don't really feel them when you wear them repeatedly). the button clips is really helpful as you can clip them together before throwing it in the washer and they will still be in tact so no more looking for the other pair while folding clothes, lol. material is comfy and cooling. and yes, most importantly it is not translucent even at the heels. some socks when pulled, the area at the heel tends to be see-through as the thread gets stretched. but not for this one.
