EVS Sports TUG Fusion Socks (Black/Hi-Viz Yellow, Large/X-Large)

Are these tall enough to tuck your nuts into ?

Does it come in pairs or a single sock?

The information is lacking. the seller has provided the most worthless responses to other questions. what size shoe/pant does xl mean?

How long are these? I am 6' 3" @ 170 with a 36 inseam, so s/m. My concern is they will be too sort.
