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.
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.
