Each of the 15 pairs of navy socks in London Sock Co.'s 'The Solid Sartorial' pack is embroidered with the label's signature penny-farthing emblem in a different colour, so you'll never have to guess which two should be matched together. They're all made from ribbed stretch Scottish cotton lisle-blend that's both soft and breathable and have tapered cuffs that keep them in place from nine to five.
