Make your feet a promise.
Castelli's Promessa Socks enjoy permanent antimicrobial properties courtesy of the silver-infused Meryl Skinlife yarns used throughout their bodies. The mesh uppers provide breathability, allowing airflow to move across your feet, while the midsoles feature a band of gently compressive material to support your foot's tendons while maintaining a secure fit. The flat-seamed toe box caps the socks with an abrasion-free fit. All of these features combined promise a long, comfortable day spinning in the saddle.
