New! Check out Hyperion, a striped sock that’s based on this construction.

Polar Arc is engineered specifically for gradient and self striping yarns. The structure exploits the properties of fabric worked on the bias and reinforced heel stitch to create a heel without a heel turn. Unlike with other sock patterns, you don’t get a break in hue or pattern across the instep because he heel is completely integrated with the body of the sock.

This sock is worked top down. The toe-up pattern is sold separately, or you can buy both of them together in the eBook Polar ARChitecture.

This pattern is structurally identical to the toe-up version with one small exception: at the very end of the arch, just before the toe, this pattern includes an additional 3(3, 5, 7) rounds of shaping. If a precise match with toe up is desired, simply skip these rounds and go directly to working the toe.

This pattern consists of 5 separate files: One file for each size (S, M, L, XL) and one file for half-sizes. When you purchase the pattern you get all of these files. Finished circumferences range from 6.5 to 10 inches.
