The Castelli Pazzo 18 Socks were designed for those who wish to brave the cold and wish to remain as warm as possible while they put in the miles. They’re Castelli’s warmest synthetic sock, constructed using PrimaLoft® and polypropylene yarns to help keep your feet warm and dry in cool weather. The thick construction under foot reduces cold coming up from the sole of your shoe, further adding protection against the cold. These features make the Castelli Pazzo 18 Sock the ideal choice for base miles in the winter time.
