These socks comprise a blend of nylon, polyester, combed cotton and elastane to create a lightweight material which is robust, stretchy and breathable. The fabric features Feel360â„¢ Technology which uses reactive fibres to encourage temperature regulation and radically accelerate moisture wicking to keep sweat and moisture buildup at bay. The technology uses silver ions to resist odour, reducing the bacteria that cause the smell by 99.95% – impressive, right?
