These are the tartan plaid socks from Corgi, the 126-year-old welsh knitwear company awarded a royal warrant by the Prince of Wales. Crafted by highly-skilled artisans, these luxurious, fine-gauge socks were inspired by the Prince of Wales check, a crossing pattern of irregular checks similar to Glen Plaid. Knit with a touch of lightweight cashmere, the flat, hand-linked toe seams treat your feet to a wonderfully soft, comfortable and secure fit. 64% long-staple Egyptian cotton, 25% nylon, 11% cashmere. Machine wash. Gray or Navy. Size S (Men’s 6 ½ - 7 ½); Size M (Men’s 8 - 9 ½); Size L (Men’s 10 - 11); Size XL (Men’s 11 ½ - 12 ½).
