Aerodynamic Performance
The key feature is the 550CX textile around the lower leg. Its textured, bi-stretch construction is designed to improve airflow over the leg while maintaining a close, wrinkle-free fit. This makes the RSR Speed Socks particularly useful when riders want some of the aerodynamic benefits of overshoes without adding another layer around the shoe.
