The Elite Ultra Light No-Show Tab Sock is Feetures' thinnest, most technically advanced sock. Thanks to the Sock-Lock support system, the sock fits like a second skin so your foot and sock become one. The No-Show Tab is designed to sit below the ankle, while the front and back tabs protect against chafing to keep the sock from sliding into the shoe. The patent-pending Power Arch is anatomically constructed to provide targeted support where it's needed most. The sock's anatomical right and left foot design further enhances the fit, delivering maximum protection by helping to eliminate blisters. Ultra-thin construction takes up minimal room inside the shoe for added fit, while high-tech iWick fibers wick away moisture to keep feet dry and odor-free. The Perfect Toe eliminates irritating toe seams for long-wearing comfort. The Ultra Light No-Show Tab Sock is made from a durable 79% iWick nylon, 13% polyester, 8% Lycra spandex fabric blend. Imported.
