No-Show Sock Test
“I may look happy on the outside but deep down, on the inside of my shoe, my sock is falling off” ~unknown 
In all seriousness though, 
the winner of my no-show sock test are the Stance brand of “Super Invisible” socks & the Lorna Jane brand of “Secret Socks” 
They don’t show AT ALL *and* they don’t fall down (on me anyway
)
