Rapha merino socks are the finest cycling-specific socks in the world. The socks use a new blend of yarns, including luxurious merino wool. This natural fibre wicks sweat better than any synthetic, keeping you cool and dry in the summer and warm in colder weather. It is also naturally anti-bacterial so, unlike polyester, the socks won’t smell after repeated use. The socks also have hand-locked seams at the toes to prevent rubbing, and are reinforced at the heel.
