Charles TyrwhittOur cotton rib socks are designed for all day comfort. Made from a cotton rich blend, they're naturally breathable and help to keep your feet cool thanks to their temperature regulating properties. Soft ribbing texture ensures a snug, stretchy fit, while seamless toes mean they have an extra smooth feel. To make sure this pair is a favorite in your sock drawer for a long time to come, we've reinforced the heel and toe.
