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.
