Made from the sophisticated ‘Merino 10’ mix of premium merino and Tencel plant-based fibres for superior all-weather performance, Feetures Merino 10 Ultra Light No Show Socks are made in the US in a durable, comfortable yet light 200N high-density knit. Feetures Merino 10 Ultra Light No Show Socks Have an anatomical fit, with patented Sock-Lock technology providing highly targeted compression and padding. The Feetures Perfect Toe creates a flat, no-seam closure that causes no irritation. The delicate Achilles tendon area is protected by a no-show tab, sitting higher than the rest of the extra-low cuff.
