Blocksox Dance Socks Experience the freedom of barefoot movement with the protection of Blochsox — the original foot undies that dancers worldwide trust. These seamless dance socks give you a second-skin fit with non-slip grip, so you can turn, stretch, and floor-work with confidence in ballet, lyrical, contemporary, jazz, modern, Pilates, and barre classes. Blochsox are made from a high-stretch, breathable blend of cotton, nylon, and elastane that hugs every contour of the foot. The patented convertible heel lets you wear them full-foot for extra coverage or fold the heel back for half-sole use—perfect for switching between styles in one class. Strategically placed grip dots on the sole deliver reliable traction without sticking, while the seamless construction eliminates irritation and visible lines under tights or leotards.
