Because humanity is rapidly reaching its expiration date, these are the Classic Calf Socks With Plus+ technology sold by Blacksocks.com. They cost $189 for ten pairs and each individual sock has a communication button that can connect to your iPhone (through an included transmitter) because this is the world we live in now.
Imagine your phone could communicate with your socks. Your phone would know:
which socks belong together,and could help sort them out,
how often you have washed your socks,
when your socks were produced,
when you ordered your socks and
when your socks were dispatched.
Your iPhone can also tell you if your black socks are no longer properly black [by taking a photo and comparing it to a chart] and help you buy new socks.
Wow, I can honestly say not a single one of those things is important to me. You know, BECAUSE WE'RE TALKING ABOUT SOCKS. Besides, the only valuable function a smart sock could possibly have isn't even included: GPS tracking to find out where that rogue son of a bitch is hiding.
Keep going for a video (turn on the subtitles).
Thanks to Todd, who can't believe they don't even have the tech to tell you how bad your shoes smell. Me? I don't wear socks so my shoes always stink like a dead animal.
