GRIPPY SOCKS FOR ON-POINT ACTIVITIES. An open-toe, open-heel design makes the NikeGrip Studio Footie Socks essential for yoga classes, Pilates, barre and any workout where it's no shoes allowed. Strategic Stability: NikeGrip technology features anti-slip yarns that provide excellent traction underfoot. The footie places NikeGrip in the ball of your foot to help stabilize your step on studio surfaces. Grippy design: the open-toe design wraps around your big toe and anchors the sock in place. The open heel allows your skin to help with floor grip. Stretchy comfort: a nylon collar surrounds the foot opening for a soft feel with a hint of stretch. A knit-in tab in the back functions like a strap, securing the fit around your ankle. Sweat-wicking fabric helps you stay dry and comfortable. Thin mesh fabric on top adds lightweight breathability.
