This sock is made of natural bamboo viscose, with a small Lurex thread running through it. This thread gives the knit a subtle sparkling effect. The bamboo feels extra soft, and its elasticity is of high quality. These socks wrap around your legs without pinching and the seamless toe area ensures that there is no irritation when worn in your shoes. Bamboo is breathable and provides optimal air circulation. The sporty rib-knit and stripes around the hem, combined with the Lurex thread, give this sock a glamorous, yet sporty look.
