And here you can see all the parts explained.
TO ADJUST THE SIZE
This picture is also useful if you plan to adjust the size of the sock to a different foot size – the main parts that need to be measured prior to making the sock are the cuff width, the back leg part and the sole part (from the narrowest point of the heel to the narrowest point of the toe). After you knit the toe part, the rest is just the sum of sole and back leg rows.
For example, in my pattern the ‘back part of leg’ has 30 rows and the ‘sole’ part has 42 rows. After I knitted the toe part, I continued with 72 rows (30 + 42) to form the ‘instep and the front part of leg’.
Also, when knitting other sizes, make the narrowest rows of the heel and toe part 4 stitches wide.

Heel

(EDIT: To make the sewing easier in the end, in the heel (and toe) rows where decreasing is involved, I recommend joining two first/two last stitches. So, for example, in Row 35, you: knit 2 together, knit 20 following stitches and knit 2 together. In the heel (and toe) rows where increasing is involved, I recommend increasing in the first/last stitch. That way no larger holes will appear and the finishing sewn seems will be neater.)
