You can never have too many socks, but we certainly have favorites that we wear more often than others. Castelli's Diverso 2 18 adds a touch of argyle style to our feet and is constructed from a Merino wool blend perfect for its application in a cycling sock. Since 1876, Castelli has tailored champions like Binda, Coppi, and Bartali. Cycling has benefited from Castelli's expertise as they brought us the first skinsuit, pockets on jerseys, and the first lycra shorts used in professional racing. Castelli is always at the forefront of innovation and is constantly looking for the best material for its products. Sometimes these come from nature and Merino wool is soft, breathable and it wicks away sweat better than synthetics. The Diverso 2 18 Socks is its thickest, warmest construction and aims to keep your feet warm in cool weather. Another feature of this natural fiber is its anti-bacterial properties keeping your feet from smelling after a long ride. Reinforced toe and heel prevent rubbing and they extend the life of the cycling sock. Merino also retains excellent warmth even when wet so you can add all-weather adaptability to its list of advantages. Add the Diverso 2 18 to our list of socks that will see constant rotation this fall and winter.
