Ultrabreathable, super-tall racing socks with targeted support for high-intensity riding in warmer climates. The all-new R Socks S9 are engineered for high-intensity riding and daily utility. Their ultralight bodies breathe, wick, and promote cooling airflow suitable for hot conditions, and the lightly compressive hold maintains a secure, slump-free fit. The 20cm (8in) race-tuned cuff doesn’t run afoul of UCI regulations. Combining a lightweight, ultrasoft yarn blend with a seamless construction, the R Socks S9 provide smooth, friction-free comfort and all-day support. Reinforced toe and heel zones add durability, while strategic arch compression stabilizes the foot during hard efforts.
