How to Use

  • Measure foot circumference at the widest part of the foot (around the ball of the foot).
  • Socks should have about 10% negative ease for a snug, non-slipping fit.
  • The heel flap is worked on half the total stitch count.
  • See the Heel Turn Calculator for the complete heel turn sequence.
  • See the Toe Decrease Calculator for decreasing to the toe.

Results are estimates. Gauge, yarn, and needle type affect actual results.
