Kilpi SPEED-U socks offer climate comfort for cyclists, runners or other active athletes thanks to the elastane knit, synthetic fibers and seamless construction. The thin, breathable material is ideal for strenuous sporting activities in summer or spring. Carefully placed functional zones offer the necessary support and comfort. The wide elasticated top edge does not compress or impede blood circulation. The fastening hem around the ankle stabilizes the position of the sock. The heel and toe area is reinforced with an abrasion-resistant double mesh. The height of the socks is above the ankles. There are several color options to choose from.
