I'm a former bike shop staff member from Taiwan. I'm dedicated to safe and comfortable rides, and I'm particular about the gear I choose every day. These are cycling socks with reflective material, especially recommended for night and early morning rides. Two reflective stripes react to rear lights, increasing visibility, which provides a greater sense of security during rides in dim light. The soles are fully treated with non-slip grip, preventing slippage inside your cycling shoes and reducing power loss. They're not too thick and are breathable, making them a well-balanced specification that's easy to use all season. Recommended for training, as well as for brevets and commuting rides. Feel free to ask any questions you may have. ☺️
