The four-leaf clover is a universal symbol of good luck. Rare and coveted, there are many legends attributed to it. We, just in case ;) have included it in our socks, because it never hurts a bit of good luck. They are made with 100% organic GOTS certified Egyptian cotton. Its fibers are long, soft and resistant, making it one of the best cottons in the world (if not the best). They are perfect to wear with shoes and formal clothes, but they are also perfect to bring a touch of comfort and distinction to any casual look. Ethically made in Barcelona.
