Sock height has definitely gone up an inch or two since my heyday and entering into the length race with the Circuit sock is US brand Bellwether.  These Coolmax knitted models come in three color ways white/black, Red. Blue to match anything in your stretch wardrobe.  With reinforced heel and toe sections and a padded foot bed the comfort is noticeable immediately with breathability to match. 

Impressively the rrp comes in at under $20 which is a full 30% less than anything else in the long cuff category that we have come across.
