Compressport Pro Racing v3.0 Ultralight Run High Socks
After developing the cycling version of the Pro Racing Ultralight sock for Joachim "Purito" Rodriguez, we decided our elite runners also deserved the same lightning-fast coolness.
Featherlight, the 9g sock provides an unparalleled second-skin feel and exceptional comfort thanks to ultra-soft mesh fabric. Ventilation is second-to-none so that your feet stay fresh and dry at all times. Specific fibres act as hot spot preventers to ensure your soles do not burn up, no matter how long they batter the pavement. Cleverly-placed, 3D.Dots on the internal malleolus protect the bone from impact for runners who tend to clip it with the opposing foot when fatigued. Targeted compression boosts blood flow, while the toe box is slightly reinforced to reduce the risk of beaten-up toes and blue nails during long, intense efforts.
If you are racing through the Saharian desert or facing a heat wave in Boston, the Racing Sock Ultralight Run is your weapon of choice.
Occasionally, without notice, manufacturers change product design and/or specifications.
