Sport is the only occasion when mid-calf socks have a place, in my opinion. As you know, visible calf between trouser and sock is perhaps the most heinous sin a man can commit in his dress, and said sin is obviously more prevalent when seated (or when wearing shorts with shoes other than trainers, though that is a special case and one for which anklets were made). It could also happen lying down I suppose, but that should be relatively rare. On the other hand, there is essentially no chance of exposing bare leg when a man is standing, and that is the time for mid-calf socks which wear cooler than their longer brethren while shooting or walking 18 holes. And for those occasions I have just the ticket(s).
Complementing my linen sport socks and stylish cotton anklets are several new styles of quality mid-calf leisure wear hose by Bresciani, perhaps the world's best maker. There is a wide ribbed cotton with contrasting heel and toe, a sturdy ribbed wool, and the ultimate sport socks: mid-calf baby alpaca socks that are lighter than wool but five to seven times warmer. Check them out.
