Hidden Contour socks by Balega deliver the ultimate protection and impact resistance with plush cushion, while offering a structured fit that contours to your foot. Engineered with Drynamix moisture management technology to wick away moisture from your skin, Hidden Contour socks keep feet cool and dry throughout every activity.

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, Hidden Contour socks offer a 1-year warranty. Balega launched in 2003 and set out to create the world's best performance running sock. Built to perfection, Balega socks are composed of extra fine yarn on high needle count machines to provide plush and protective cushioning, without adding bulk.
