The sock weight (or yarn weight) refers to the fineness/thickness of the yarn used in the knit. We currently have 4 different sock weights; from lightest to heaviest, they are Ultra-lightweight, Lightweight, Midweight, and Heavyweight.
These combine with our 3 cushioning levels to create a range of support, warmth, and comfort in our socks. Try different combinations of cushion and weight to find the perfect balance for you.
