Combed cotton is a type of cotton whose fibres have been brushed in order to lengthen them and make the fabric even softer, ensuring greater quality. Socks made from this type of fabric are stretchier and more pleasant to wear.
A material called elastane is used to make the sock stretchy, offering superior support of the foot. Please note: your socks may appear smaller but this is in fact just due to their increased elasticity. Withstands repeated washing better.
