I'm 6ft 2", 19.5" and wear a size 13 Adidas flip flops. This is a comfortable fit. The healing on this sock goes most of the way down my foot and it's imperceptible. The sock comes down to my knees; I prefer not to fold them, but I can let them fall to mid-calf if I really want to. They're thinner/lighter than the Nike Classic IIs I usually buy, but also half the price, so a decent price. I don't know how long they will last, so I can't rate durability. Update (9/16/2021): Almost a year later I still love these socks but they tend to fall off compared to other socks I usually buy. -- my US Soccer Referee socks do the same. Because of this, I don't wear them as often as other socks. They are still in good condition but I don't wear them every week during football season so I expect them to last a long time. They are still "value" socks more than "performance" socks but I would buy them again if I needed the color they just came out in or the others at the time I did they needed were not available.
