Am I the only one with a lot of single socks? I think my washing machine eats them. No I am not. For $189, Switzerland-based Blacksocks will send you 10 sets of these “Smarter Socks,” complete with radio-frequency ID buttons attached to each cuff. To locate a sock’s partner, simply hold the included wireless reader, dubbed the “Sock Sorter,” over the first sock’s RFID button. Then, wave the device over a mound of clean laundry laced with solitary socks. When a match is found, you’ll hear a beep.
Very expensive, but if I would have the money ... I wouldn't buy it ... to much of a hassle.
