The Kilpi SPEED-U socks offer climatic comfort for cyclists, runners or other active athletes thanks to the elastane knit, synthetic fibres and seamless structure. The thin and breathable material is ideal for intense sporting activities in summer or spring. Carefully positioned functional zones offer support and necessary comfort. The wide elasticated top hem does not compress or hinder blood circulation. The fixation hem around the ankle stabilises the position of the sock. The heel and toe area is reinforced with a double abrasion-resistant knit. The height of the socks is above the ankles. There are several colour options to choose from.
