We take the leg portion of our TT shoecover and stitch it to our most comfortable sock for in-shoe comfort. It's the same as the aero sock we supply to Team Sky, and it's a riders' favorite.Also available for customization in our Servizio Corse program.

- The sock portion is based on Castelli's Rosso Corsa sock for in-shoe comfort
- The leg portion is constructed with engineered grooved Lycra® to help detach airflow
