Generally, your shoe size is a good indicator of what sock size you will fit. Darn Tough size charts (above) show the sock-shoe size conversion for our men's sock sizes and women's sock sizes, as well as for unisex and kids socks.

Sock Height

Sock heights are relatively universal. We admit we invented Micro Crew on our own. The below visuals can give you the general idea, and the sock lengths chart will help with specific measurements.

Sock Height by Inches

We measure from the heel to the cuff of the sock. A ruler or measuring tape can help you determine where the sock will reach on your leg, but results may vary based on your individual leg length.

Sock Cushion

Cushion is a padding within the sock created by knit terry loops. The cushioning provides added protection in high impact areas, shock absorption, and extra warmth and comfort.

No Cushion Socks: A thin knit with no lift from terry loops in the socks. Regardless of yarn weight, this is a thin sock.
Cushion Socks: Terry loops underfoot and other areas of the sock, but does not wrap the foot. Our most popular, versatile cushion style.
Full Cushion Socks: The terry loops run the entire length of the sock, or at least up to the cuff, for a full wrap of cushion around the foot and leg.

Merino Wool

Naturally evolved over thousands of years, we choose Merino Wool for our socks because it’s wildly resilient and incredibly versatile. More often than not, it’s not wool you're allergic to, it’s the kind of wool you’re wearing. Merino Wool is soft and comfortable.

The “still” in the Still Made in Vermont, USA is a personal thing. We’ve been running the Mill for over 40 years, but Darn Tough Vermont – the sock unconditionally guaranteed for life – started in 2004.
