Blacksocks is a European men's clothing subscription service and online retailer founded in 1999, specializing in luxury socks, underwear and t-shirts.[1] With no requirement to pay in advance, customers receive a fixed quantity of socks at regular intervals of 1–4 times annually, charged to a payment method of their choice prior to each shipment. The yarn for the socks is spun, finished and dyed near Milan, Italy and then sent to Barcelos, Portugal where they are all knit and packaged for shipment.[2] The socks come in a limited variety of colors and styles—typically only sneaker ("no-show"), crew or knee length—that are made of cotton (either 100% organic or blended with mercerised and Pima), pure Merino wool or a 65/25/8 blend of modal, polyamide and cashmere.[3]
