Mouse over each portion of the sock on the left to discover the unique construction and features of Sierra Club socks.
Extra fabric is added into the toe area using a knitting technique known as reciprocation. This creates more room for the toes and adds extra comfort.
Virtually seamless, our Lin-Toe closure is the smoothest, most comfortable toe seam you can buy. This mechanically-linked closure is seamless inside the sock as well as outside, since a single thread joins the two opposing fabric edges loop-for-loop, creating a single piece of fabric. This method also eliminates significant waste over conventional production, since much less fabric is used.
Our cushion sole socks include extra padding of "sandwiched terry" construction-a higher grade of fabric than found in most cushion sole socks. This provides superior comfort, moisture management and foot support.
A knitting technique known as reciprocation adds extra fabric into the heel area. During this process, the knitting machine oscillates, creating the reciprocated heel.
To protect the back of the foot where it contacts the shoe, we add extra reinforcement. This also gives the sock greater durability.
Where the leg transitions into the ankle, becoming smoother and not ribbed.
Different from woven fabrics, knit fabrics offer enhanced elasticity; we use it in our socks for increased breathability, comfort, fit and warmth.
The visible part of the sock, it is often seen between the shoe and the pant leg. Different legs are created for different uses, but all of our legs are focused on comfort, fit and style.
Most Sierra Club socks feature a "true rib," created using a dial machine where the sewing needles oppose each other, knitting a ridge right into the fabric. Simpler socks employ a "mock rib," which uses a rubber inlay to create the appearance of ribs.
The cuff of our sock features a double layer of fabric to improve its appearance and help keep it from sagging down.
