A good pair of socks keeps your feet warm. A great pair of socks does it with a dash of outfit-boosting color, extra-soft fabric, and construction that'll keep ‘em stepping for years to come. These Italian-made Mercerized cotton socks from Etiquette Clothiers have all that and then some. This type of cotton — also known as filo di Scozia, or “Scottish thread” — is produced on 200-needle machines and carefully treated to change its underlying chemical structure. The process results in a slight, silky shine and extra durability.
