These Smarter Socks from e-tailer Blacksocks will cost you a whopping $189 for a pack of 10. But for the extra bucks you’ll never have to guess how to match your socks again, thanks to the RFID chip implanted in them that talk to your iPhone. Once you download the Blacksocks app to your phone and pair it with each sock it will help you find the sock’s match, tell you how long you’ve had them and if you hover your phone over the sock it will tell you when it’s time for a new pair. You can order the new socks right off the iPhone, run!Via.TheLifeFiles
