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.
Ultra-lightweight Socks: The absolute lowest profile that is nearly a second skin. Even with cushion, these socks are sleek and silky smooth.
Lightweight Socks: The most versatile weight found in practically every sock category. When accompanied with cushion, it is considered the most sublime combination.
Midweight Socks: With the outdoors in mind, this is where Darn Tough's hiking socks and ski socks made their name. More natural insulation, and so durable they are a thru-hiker staple.
Heavyweight Socks: Our warmest socks. Always with cushion, if not a full cushion of terry loops, these usually have the highest Merino Wool content of any style with maximum Merino benefits.
