Step-by-step crochet instructions
Create a foundation chain of 14 chain stitches and one returning chain.
1st row (right side) - single crochet to end, then one returning chain (RC) and turn the work.
2 - 25 rows - back loop single crochet (BLSC) to end, then 1 RC and turn.
26th row - BLSC to end (do not create 1 RC).
Connect two ribbing ends together.
Insert the hook into the first stitch of the opposite end of the ribbing, grab the yarn, and pull it through both loops. Then insert the hook into both second loops from the yarn, do yarn over, and pull it through the 3 loops. Repeat the process to end. Flip the work to the wrong side (now it will be your right side) to hide the seam.
On one edge of the ribbing pick up 38 chain stitches while working single crochet.
BLSC for 2 more rounds.
1st row (right side) - BLSC for only 20 sts, then 1 RC and turn the work.
2nd row - reverse front loop single crochet (RFLSC) for the 20 sts, after that do 1 RC and turn.
3rd and 5th rows = 1st row.
4th row = 2nd row.
6th row - RFLSC to end and turn the work.
To decrease one chain stitch (1D), create 2 loops in the following 2 chain sts from the hook and pull the yarn through the 3 sts.
7th row (right side) - 1D, BLSC to last 2 sts, then 1D and turn the work.
8th row - 1D, RFLSC to last 2 sts, 1D and turn.
Alternate 7th and 8th rows until 7 stitches left.
Begin to crochet in round. Start the round with BLSC for 6 chain stitches.
Then pick up 6 sts on the left heel side of the sock while continuing single crochet.
BLSC for 18 chain sts.
Lastly, finish the round by picking up 6 last stitches on the right heel side. You should have 36 chain stitches in total.
Work BLSC in round for about 24 rounds or, depending on the foot size, until you reach the desired length of the sock.
1st round - [1D, BLSC 4] to end.
2nd round - [1D, BLSC 3] to end.
3rd round - [1D, BLSC 2] to end.
4th round - [1D, BLSC 1] to end.
5th and all the rest rounds - decrease without intervals.
Cut the yarn, insert it inside of the sock, and secure the tail of the yarn.
