For runners seeking plush cushioning with a supportive structure, Balega's Hidden Contour provides cloud-like comfort combined with a compressive arch band that hugs the foot and keeps the sock in place. Engineered with Drynamix moisture management technology to wick away moisture from your skin, Hidden Contour socks keep feet cool and dry throughout your run, no matter the distance. The socks have been race tested and incorporate a seamless toe, eliminating abrasion across the top of the foot preventing hot spots and blisters.. Hidden Contour socks feature an extra deep heel pocket to ensure that the socks fit your foot perfectly and won't slide down your foot during a run. Proudly made in the USA.
